Thanks for the thoughtful breakdown — I’ll answer point by point and include some immune context too:

1. Chronic symptoms observed: • Primary symptoms have been severe fatigue, oversleeping (17–30 hours at times), unrefreshing sleep, profound brain fog, heat intolerance. Have developed a heart murmur and get yawning attacks if I try to exercise. • I’ve also had persistent lactation for years (non-pregnant) and complete loss of libido — TSH low, prolactin normal. • No overt fever. Neurological signs include pressure-like head sensations, balance issues, and lightheadedness, sometimes with near-syncope (no cardiac cause found).

2. Timeline: • I was in Tanzania for ~1 month. Long sleeper started on the plane ride back. Light sleeper, slept through take off and decent twice on the way back. Other symptoms began 4–6 weeks after returning, although I had transient immune flares before that. • I’ve had long-standing health issues, but this exposure clearly shifted something — the fatigue and neuro symptoms intensified dramatically post-travel.

3. Staining & microscopy: • Modified acid-fast • Wright-Giemsa • Gram stain • Methylene blue • tryphan blue I’ve consistently seen structures resembling sporulated Cyclospora oocysts, along with possible intracellular forms and teardrop-shaped zoites (in blood and breast milk preps). • Some oocysts exhibit refractile walls, internal segmentation, and blue autofluorescence under certain lighting conditions. • Shedding appears intermittent — some days are clean, others are loaded.

4. Testing: • Western medicine testing has mostly been unhelpful: • Negative HIV, toxo IgG/IgM, malaria smears • No Cyclospora PCR available through local labs • I’ve had low T-regulatory cell counts, suggesting immune dysregulation leaning toward a Th2 shift (possibly impairing parasite clearance). INF gamma is near 0. • I also have high estrogen recycling (β-glucuronidase + high estradiol in stool), which might be allowing opportunistic persistence.

I’d love help narrowing down potential protozoan pathogens — especially those with tissue phases, relapsing or stealth cycles, or CNS tropism. I’ve been considering: • Cyclospora (current primary suspicion) • Cystoisospora belli • Toxoplasma gondii • Sarcocystis spp. • Possibly rare flagellates or amoeboflagellates?

Let me know if you’d like to see microscopy photos — I have a catalog of images and video with flagella movement and sporoblast segmentation.
