i have chronic pain over my entire body, sometimes my skin feels like it is on fire. i cannot sit, stand or lay down for any length of time. i have been to neurologists, neurosurgeons, rhumatologist and have had lots of blood work, and scans, nerve and muscle tests. all results come back normal or negative. can you please advise what to do next? i have had 2 drs tell me that i am a puzzle that they can not figure out. i am starting to get depressed and it is affecting my ability to do my job.
