So just a little while ago I noticed this bruise on my belly. Also have been feeling this sorta pressure right where i circled on the full body pic. Its not gas as i have been trying to pass it for a while and nothing. About a week ago i noticed i had a weird pain on my wrist and i touched the spots and the vein felt swollen? The spot now has a bruise. I’ve also been having little sharp pains in my chest and shoulder blade. Sometimes sharp pains in my back lately. Idk but lately I’ve just been extremely moody and nauseous and tired. Anyone have any idea on what’s been going on and what could be wrong?
