Hey there, friend.
IBS can manifest in a variety of different symptoms. Funnily enough I have it and so has my mother. While I fight with some ugly periods of bad bloating/blunt pain and dirrhea, my mother mainly fights with a sharp pain in the lower side of her intestines. I get those pains that feel like needles really rarely and thankfully I can really manage them with the right kind of careful self-massage.
So yeah, it could be IBS.
