had a pain in upper back since last monday, feeling like trapped nerve, eases off for while, putting hot water bottle on when it more painfull, then last night app, 3am, the pain was in my chest, had to get up take paracetamol and re heat water bottle, propped up in bed, then eased off, wasn`t to bad when got up, as day gone on pain increased again in chest, was going to contact my gp, but it was too late, no appoitments. just to put my mind at rest,, as last night was scary, it felt like a heart attack, but i dont know what heart attack feels like, i will contact my gp in morning if pain continues. thankyou
