From my previous post: I was diagnosed with POTS in 2010, they did a tilt table test to diagnose me, they ruled out other d/o first, As far as blood tests: I had a CBC, BMP, blood cultures. I did not have a LP or any other body fluid testing. I was never tested for environmental factors, ex heavy metals etc. I have seen a EP, and neurologist at UCSF. The memory issue the neurologist was not concerned with. I am still having memory issues as well as the previous listed problems in my last post. most recently i am having another symptom, i dont believe it is r/t my POTS. I have been having blood tinged jelly like mucous coming form my rectum, it comes out whether i void or have a BM. My BM range from daily to once every other day, sometimes i may have 2 a day. Most recently I have been having horrible pressure on my rectum when i sit, and i have a spot along my tailbone that has a visible bruise. Any thoughts. I just seen my PCP and have a referral to a GI doctor at the end of the month, i have pending CBC, BMP, and stool cultures.
