Hi, I am a 35 year old male, for the past couple of weeks i have been feeling nauseated and mild diarrhea. the nauseous feeling seems to go away slightly when i eat or drink something. dont get me wrong i still kinda feel it but not as much. I do smoke some recreational marijuana every now n then. dont know if that has anything to with it and also i randomly got this lump on my chest and its tender to the touch about 2 inches in diameter
