For the past two weeks I had chest pain. Everyday sometimes light pressure others heavy pain as if heart is being tightly squeeze. Had sporadic heartbeats, skipping or fast beats lasting seconds. Also felt heavy load pain on neck, shoulders and upper back. During my regular weekend hike, this week I had a strong episode, in seconds my heart was beating out of my chest, cool sweats, light headed. I'm 42, 5-7, and 235lbs otherwise generally healthy. I was diagnosed with fybromailgia 4yrs ago only take over-the-counter meds. Also diagnose as a child with ITP in remission since the age of 11. Lately I have notice a large increase of petequia all over my body, pin size to 1/8"d. I wonder if this chest/heart pain is related to my conditions or need further assessment? Thank you
