Strong Headaches Almost A Week, shingles?

On my second round of meds (ivermectin, praziquantel, Pyrantel Pamoate) and I've been getting these severe headaches with burning and itching also involved. Also been getting a lot of rash especially this one 4 inch rash on my shoulder that looks like shingles (a bit of numbness is also involved but I've resisted any scratching). Was just in the ER last week for chest pains and headache now it's the strong headaches, burning, and itching. Also seeing a lot of Tapeworm segments and rice seeds in my stool lately so I'm not sure what's going on. I just don't want to go back to the ER and they tell me nothing useful. At first I thought the parasites had escape to my ears and brain but then the rash breakouts and burning and neck pains came out of nowhere. Any advise would be appreciated. Have already done two coq10 megadoses and vitamin C. L-Cystine seems to help a little bit. I ran out my antiviral herbs that should be coming Tuesday but I really hope I don't have the shingles! Tweet
