I am currently experiencing pain in my lowever right stomack and I can feel a round knot. The pain is pretty much centralized to that one spot. I was recently told I was allergic to cow s milk and today I ate a breakfast sandwhich that contained whey. But this seems like it s lower near my fallopian tube. I was also told I had a cyst before but I can t remember exactly where that was and it was only the size of a pencil eraiser
