i am 54 yrs old female with fibromyalgia and arthritis, I have lately been struggling to climb stairs and getting really breathless like I am going to pass out as I fight for breath, this evening I have a annoying chest pain and in my jaw not like a toothache, today I had to go to bed at 4pm as I felt exhausted, I had been in the office since 10am till 2pm, not doing anything strenuos or stressfull I slept untill 8pm and felt better but just before I had the weird pain just sitting here.
