The photo of proglottids look similar, but I don't think that's it.
These "things" very closely resemble photos of toxoplasma, toxoplasmosis gondii. But, it's always said that toxoplasma are microscopic. The "things" that come out of my skin, when the skin is massaged with mayonnaise, range in size from very small specks up to 1/2 long. Certainly not microscopic.
Shroom, how, where, do I go to have them analyzed? I will do it if I knew how and where to go!
