Hi, recently in the last few months or so I feel like something isn t right with my body sometimes it feels like it is trying to shut down, I never used to get ill it now it s becoming a regular occurrence. I get a lot of flu like achy symptoms and regular sharp pains around my body in my chest more than anywhere else, regular I wake up at night and my chest in pounding so hard it physically hurts, could this be leading up to something serious?
