Hi elena gee, I've found the answer it's a condition called Costochrondritis,
Painful information of thorax or ribs, sometimes causes heart to race, happens with FIRO when you try to do to much, especially with change in the weather, pacing helps to avoid this symptom.

I read on fybromyalgia site that you get pain around your chest, breast bome and ribs but can't remember what it's called I will get back to you x

Thanku so much Denise

Sounds crazy but Gas x and wintergreen mint's help me takes the pressure away for a while.

Oh yes please and thanks x
