I put my son on Humaworm and he had sinus and ear problems after two weeks. I believe this was parasites. I have them in my sinuses and ears as well. I also believe that the parasites squirm when they are dying but also when they are agitated. I took Albenza a two time dose in two weeks and some died but others were very agitated and are still wiggling after a month. I tried Humaworm but quit because it got so bad. I'm not sure how any of you could put up with the squirming! I couldn't sleep and it was driving me nutty. I've been off Humaworm for over a week and they seem to be calming down somewhat but I know that I need to kill them so I am hoping to get something stronger that will knock them dead without much movement. But, I also think I have a severe case. Keep doing what you are doing if it doesn't get too bad.
