Pain, tingling and fatigue

Hi I have been to so many doctors/specialists for almost two years trying to find answers for my tingling, fatigue and pain. PCP, chiropractor, spine doctor, two rheumatologists, neurosurgeon, neurologist. Two years ago i had our last child after multiple miscarriages and then IVF, along with a difficult pregnancy and birth. Two months later i got horrible spasm like chest pain in the middle of the night while i was up feeding the baby. It was so bad i called 911, they took me in to get checked but my heart was fine. (I had preeclampsia with that last pregnancy so they did an overnight observation) i had had pains like that in the past but they did not last as long. After this issue i started having tingling in my mid back off and on when im doing an activity where im slightly leaning but also using my hands. i also developed more neck pain then usual and pain in my arms around my elbows (not necessarily my elbow joint) and also a face rash . I went to a chiropractor that didnt really help. My dermatologist checked my ANA which was a low positive titer and he said prob not lupus, rheumatologists also said not lupus because the rash didnt go in the folds of my nose. Next i went to the spine dr after my first MRI, he gave me a steroid shot to the beck, it helped my neck some and my arms tremendously however the tingling in my back actually flared from it. Once it wore off it all came back. I mostly feel the pain in my arms when i’m using them and my hands in conjunction, like carrying bags, lifting 8lb dumbells, using a shovel, drinking from cups etc. i’ve had two episodes of tingling in my hands early in the morning out of nowhere and one episode of finger fasculations on my non dominant hand. I had tingling in my feet a few times and my calves but that has stopped. My right leg buckles frequently way more than in he past. I’ve had tingling and numbness in my left thigh for years. Ive had issues using utensils at times when eating or shredding meat, my hands cramp up along the pinky sides on both hands. I can not text or write for long periods like more than 5-10min (been years for this but never saught a doctors opinion) I also have difficulty chewing certain things, my jaw muscles get tight.
I went to a neurosurgeon to see if he could fix my neck hoping that was the cause of my issues but he said my neck wasnt bad enough, but when looking at my MRI he said a white area on my spinal cord and thought maybe i had MS or something and sent me to a neurologist. Neurologist was not helpful at all, did not check my brain or order any additional testing. He saw my second mri which didn’t show the white area on my cord and wouldnt look at the original at all! His answer was treat my symptoms with no diagnosis like it was fibro but that it wasnt fibro…oh i also had a normal emg of my arms and left leg. Im at a loss and want to give up any hope of figuring this out. Has anyone has this experience? Sorry its all over the place I was trying to think of everything at once, I know i’ve missed some details.
