I have had the thumping too in my stomach right under my rib cage!!! I didn't start feeling it until after the albenzole! At first I thought maybe it was my stomach muscles moving back (I have a 5 month old and I've been working out a lot) then I thought gas now then I freaked and thought maybe I was pregnant again too because I am still nursing! Now I'm not sure at all! I can't do a lot of the cleanses because of nursing. I feel like it is definitely something dying off that I'm seeing in my poop! I'm just wondering what the hell it is and how long it's going to last for? All I went in for was pinworms now I feel like I've stirred things up I was totally unaware I had...at this point I wish I was still unaware! I have been taking acv everyday for about three weeks so I'm wondering if it is mucous/fungus? I don't freaking know but I'm OVER IT. I don't want to even get "close" with my husband because I am paranoid of spreading something that I don't even know if it is actually something. I'm going crazy, that's it just crazy! I'm 25 and OCD super clean, like why is this happening?
