I'm 20 years old and i have this weird burning and tingling sensation on the left side of my ribcage. It burns in the front and tingles in the back. For about 2 weeks now i have had tinging in my left arm as well. The other stuff has been going on for about a year in a half and i have asked doctors about it and they tell me it might be a nerve. I need some answers for this please if any doctor can help i would appreciate it.
