The literature also refers to different stages of the lesions based on color - clear, white, tan, red, black. The different stage can produce different effects on the amount of pain and inflammation it causes.

"Acid-sensing ion channels (ASICs) can detect a broad range of physiological pH changes during pathological and synaptic cellular activities...Activation of ASICs is involved in pain perception, synaptic plasticity, learning and memory, fear, ischemic neuronal injury, seizure termination, neuronal degeneration, and mechanosensation. Therefore, ASICs emerge as potential therapeutic targets for manipulating pain and neurological diseases. The activity of these channels can be regulated by many factors such as lactate, Zn2+, and Phe-Met-Arg-Phe amide (FMRFamide)-like neuropeptides by interacting with the channel’s large extracellular loop. ASICs are also modulated by G protein-coupled receptors such as CB1 cannabinoid receptors and 5-HT2. This review focuses on the physiological roles of ASICs and the molecular mechanisms by which these channels are regulated." http://www.ncbi.nlm.nih.gov/pmc/articles/PMC4133903/
Estrogen can potentiate the action of ASICs.
"E2 potentiated ASIC currents via an ERα and ERK1/2 signaling pathway. E2 also altered acidosis-evoked membrane excitability of dorsal root ganglia neurons and caused a significant increase in the amplitude of the depolarization and the number of spikes induced by acidic stimuli. E2 potentiation of the functional activity of ASICs revealed a peripheral mechanism underlying this sex difference in acetic acid-induced nociception." http://press.endocrine.org/doi/abs/10.1210/en.2015-1557?journalCode=endo#sthash.0DpqNTD7.dpuf
Pain causes fatigue through similar means. Testosterone seems to lessen this effect.
"Chronic pain and fatigue often occur together -- as many as three in four people with chronic, widespread musculoskeletal pain report having fatigue; and as many as 94 percent of people with chronic fatigue syndromes report muscle pain. Women make up the majority of patients with these conditions..."The differences in fatigue between males and females depends on both the presence of testosterone and the activation of ASIC3 channels, which suggests that they are interacting somehow to protect against fatigue," Sluka said. "These differences may help explain some of the underlying differences we see in chronic pain conditions that include fatigue with respect to the predominance of women over men."" https://www.sciencedaily.com/rel.../2008/04/080407153037.htm

"In the genetic regulation of Müllerian structures development, a key role is played by Hoxa and Wnt clusters, because they lead the transcription of different genes according to the different phases of the organogenesis, addressing correctly cell-to-cell interactions, allowing, finally, the physiologic morphogenesis. Accumulating evidence is suggesting that dysregulation of Wnt and/or Hox genes may affect cell migration during organogenesis and differentiation of Müllerian structures of the female reproductive tract, with possible dislocation and dissemination of primordial endometrial stem cells in ectopic regions, which have high plasticity to differentiation. We hypothesize that during postpubertal age, under the influence of different stimuli, these misplaced and quiescent ectopic endometrial cells could acquire new phenotype, biological functions, and immunogenicity. So, these kinds of cells may differentiate, specializing in epithelium, glands, and stroma to form a functional ectopic endometrial tissue. This may provoke a breakdown in the peritoneal cavity homeostasis, with the consequent processes of immune alteration, documented by peripheral mononuclear cells recruitment and secretion of inflammatory cytokines in early phases and of angiogenic and fibrogenic cytokines in the late stages of the disease." http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3697788/#!po=2.17391

What can I say? It's complicated.
Endometriosis is an inflammatory disease, so a lot of people have questions about blood tests that look at inflammation. Let's look at what inflammatory markers are and specifically at CRP:
"Serum proteins that are produced in response to inflammation can be referred to as inflammatory markers. These proteins are mainly produced by the liver in response to stress and can also be called acute phase reactants. Pro-inflammatory cytokines such as IL-1, IL-6, and TNF-alpha induce synthesis of some acute phase reactants that include CRP, fibrinogen and haptoglobin. Other proteins, like albumin, are not sensitive to inflammatory cytokines for increased synthesis; instead chronic stress (inflammation) results in a lower synthesis rate with resultant decreased serum concentrations. The inflammatory markers are not diagnostic of inflammation, but reflect abnormalities that are seen in autoimmune diseases, infections, malignancies and other illnesses.
C-reactive protein (CRP)
So what does this have to do with endometriosis?
Remember, all these tests might be a mere indication of endometriosis, but they are very nonspecific. The only way to accurately diagnose endometriosis is through surgery.
Mast cells:"Mast cells may contribute to the development of pain and hyperalgesia in endometriosis
The presence of increased activated and degranulating mast cells in deeply infiltrating endometriosis, which are the most painful lesions, and the close histological relationship between mast cells and nerves strongly suggest that mast cells could contribute to the development of pain and hyperalgesia in endometriosis, possibly by a direct effect on nerve structures.
Researchers set out to detect and quantify mast cells in peritoneal, ovarian, and deep infiltrating endometriosis and to study the relationship between mast cells and nerves in endometriosis.Excision of endometriosis from different anatomical locations was undertaken in 69 women, who were undergoing laparoscopic excision of endometriosis for pain. Thirty-seven biopsies of normal tissue were obtained from women without endometriosis.
The women with deeply infiltrating lesions had significantly higher preoperative pain scores than women with peritoneal or ovarian endometriosis. Mast cells and degranulating mast cells are significantly more abundant in endometriotic lesions than in non-affected tissues. Deep infiltrating lesions show a significantly higher number of mast cells, activated mast cells, and mast cells located <25 mum from nerves than peritoneal and ovarian lesions. The authors found significantly more degranulating mast cells in deep infiltrating lesions than in peritoneal lesions.

"Tissue of DIE and SE appears to have similar stem cell-related genes. Nevertheless, there are differences in gene expression between SE and DIE." So the stem cells of superficial and deep infiltrating endometriosis are similar but the gene expression is different. So what causes the deep infiltrating to be expressed differently? Hormonal influence? Diet? Toxins? http://www.ncbi.nlm.nih.gov/pubmed/26426155
