i am 23 years old female and im having a pain in my upper abdomen, on the right hand side, just under my ribs and its a burning, dull aching kind of stabbing pain sometimes, feels like muscles but im not sure? i felt this when i was in my third trimester with my son but i cant be pregnant because im on the implanon. my skin almost feels numb and i am bloated (dunno if thats related) but also the skin almost feels numbish and it can get worse when i eat and i feel when im sitting down sometimes i need to stretch upwards to feel better temporarily, or put my arm across where it hurts. i was wondering what its from, i thought maybe IBS but now im not too sure? thank you in advance for any help.
