hello I have two questions. 1.Since of recently(week), I have had this weird feeling in chest(at times, it hurts like a pinch, and at times it feels like a sprained muscle). Also my left hand has been weird, it feels sore at times, like how you would feel after working out( I have not been working out). sometimes there s a dull pain(nothing significant, but I can feel it) what could this be? 2. There are a couple of lumps, I can feel on my right hand. Now this has been there for a few years.. no significant enlargements or anything, but it is there.. Should I be alarmed?
