Recently Ive been having ringing in my left ear (very mild and short term nothing too bothersome) and also weird vision spells where my eyes feel like they focus on too many things at once and go kind of sporadic all of the sudden. (i have an astigmatism but have never had any problems before as i wear glasses and contacts) i just found a small bump near my left temple and its kind of sore like when you bump your head. im very concerned!!
