If pain is mainly on right side, or worse after an injury...I wouldn't think it is fibro related.. you could have fibro plus something else..

I would seek out a highly skilled MD or DO might be better as they tend to look at whole body more than MDs, or possibly expert naturopath, or possibly expert chiropractor..

We have a Fibromyalgia forum with useful sticky threads or here is a current websearch with info on fibro.
Fibromyalgia - Google Search

From what I read on fibro years ago, what you mention about doesn't really fit..
I have a similar thing-
chronic myofascial pain - Google Search

[Any injury will cause me severe pain for 2 day to 2 weeks]
You might explore our RSD/CRPS forum also if you haven't yet..

I may have missed past posts that have more information on your symptoms & health history...
