hi there, i'm having excruciating chest pain and upper back pain (in between my shoulder blades) this lasts anything from an hour onwards and makes me sick, leaves me with no energy and makes my body all tingly, also find it hard to breathe. I have been getting treated for gullet spasms and depression but have recently noticed that my depression, chronic chest pains, headaches and migranes and constantly feeling sick always happens during or just before i start my periods. i am currently on the marina coil and also had a miscarriage at the beginning of last year so i dont know if that could be causing anything, i just need an answer as can not deal with the pain any longer.
