No one on here is going to be able to tell you if this is Fibro; only a doctor, after doing the pressure point checks, would be able to diagnose you. You need to have pain in 11 of the 18 pressure points in order to have the diagnoses of Fibro. See your doctor. Normally a Rheumatologist would be a doctor to diagnose this, just to let you know; it falls under their specialty.
I'm sorry to hear your in such pain and I know how you feel. I have been told I have fibromyalgia. I have back, shoulder and many other areas which cause pain but I agree with the other person grendslori who said to see a doctor. I have had these pains for many years and it is only recently it has been diagnosed. Don't put things off or struggle it may be something else that could be helped quickly with the correct help like trapped nerves as an example.
There are also other symptoms to fibromyalgia like fatigue and fibro fog (forgetfulness). So you need to be checked by your Doctor. Good luck,
Wishing you well.
