I've had alot happen in the last few years and been on alot of antibiotics plus steroids etc.. I have noticed strange things like chest tightness,whole body heaviness,twitches and swelling feeling plus confusion and light sensitivity.I have been to see a rheumatologist,neurologist,primary care,ent and dermatologist and vascular doctor so far no one can say anything but possible fibromyalgia.I am really concerned about the feeling of being swollen especially when it happens in my head I feel like I can't comprehend or I am in outer space and when this happens it brings on a panic attack.Does this sound like fibromyalgia or fibromyalgia mixed with something not detectable with blood tests,emgs,ekg's,ecg,nerve conduction tests,brain mri,c spine mri.
