Constant sporadic needle pain throughout the body without cause

[tristang]

Over 2 years ago I had a severe drug reaction (DRESS syndrome was the diagnosis after 3 hospital visits in 2 months). In the first 6 months, after leaving the hospital my body would rash out once off all steroids and i had extreme peeling of my entire body. I was given an immunosurpressant  called cyclosporine which helped keep the psoriasis like rashes away but I had persistent red bumps which didnt itch, but would spike in pain under stress/ excessive activities like carrying a lot of heavy things. Cyclosporine was never seen as a permanent treatment and my doctors wanted to wean off. About 6 months since beginning cyclosporine my condition changed to be much more needle pain than rash, and i stopped getting psoriasis like rashes altogether. the needle pain would come all the time, much less in very cool places like my dorm room, much more often in the sun. About a month after I had gotten strep throat, which isn't surprising because I was on an immunosurpressant and  my doctors told me my immune system would be compromised going forward after the DRESS reaction. but after the strep throat the needle pain became much for persistent. To the point anytime going out in the sun would begin great needle pain which would build up in my arms and then spike in my chest till i feel crippled in pain. Red dots would occasionally spread on my arms from its persistent location on the inside of my elbow and the localized area around it. This crippling gave me a lot of panic to the point I had to medically withdraw. The constant pain and persistent increase in any stressful situations, any type of physical exertion, and anytime being in the sun has led  to me having persistent headaches, inability to concentrate, high constant anxiety, and inability to function like work/take classes. I have had many treatments from topical creams, xolair and gabapentin for a possible idiopathic illness, amitriptyline, buspirone, cymbalta, and now have just started lyrica. Every single drug, except buspirone (which helped a little with severe anxiety but nowhere near treats it), has had no effect on my condition. I have run tons of tests like blood tests, and emg/autonomous, which have all came up negative for any issues but loss amount of vitamin d because im not in the sun. My doctors have really no idea what is causing this pain, have been unable to give a diagnosis, and are really unsure where do come from here. The pain is seems nueropathic because its pins and needle but pretty much everything leading to that has been negative so im pretty unsure. If lyrica doesnt work, the only ideas I personally have is to go on another immunosurpressant. Im really not sure what could cause needle pains randomly and constantly throughout the entire body, and spike in the sun/anxiety. Important to note it is not primarily in my hands and feet. I do have harsh peeling on my feet ever since the hospitalization that after showering leads to a cutting pain but I think that's separate.  My biggest issue is its feels impossible for me to make any progress because the needle pain affects me severely in functioning normally. I cant go outside without being in a nervous state because i can feel the needles begin to get worse and worse. I am pretty confident that I am not making them worse but anticipating it, I have spent a lot of time working with a psychologist to have good breathing and calmness concerning my condition, and have had a good mentality in the 2 years I have had this. Its just so limiting in being able to work as I get headaches, easily forget things, and get dizzy any time I try to do work or accomplish a tough task to me (normal task for other people like call someone, send out an email, read and comprehend a lecture/ chapter. I have no issue giving up time if thats what the illness takes, but sitting idle isn't the best for me and now that my doctors are unsure im trying to reach out to see if anyone else has any ideas. Its very difficult facing something when u have no idea what it is, and no one else does, and thats a very isolating feeling that really gets to me when I try to think of the future.

Have you had any recent blood tests done? If yes, was it all normal? B12 levels?

all tests were normal but low vitamin d levels which is a result of not being in the sun and have been taking vitamin d supplements since the results
