Neuropathic pain. What do i do?

So for the past five months I've been having these weird sensations in body. I was stressing a lot in October and I don't know if it was that but it triggered what we can call pins and needles sensations. I was really scared and consulted a general practitioner about it who suggested me to get my vitamin b 12, vitamin d, calcium and thyroid checked. My calcium and thyroid were normal. Vitamin b 12 was also normal with a value of 269 and vitamin d was insufficient with the value of 22. Meanwhile, I also had a hair loss problem and got to know that my ferritin is 5, while my haemoglobin has always been normal. I've been to a lot many doctors and they all tell that it is either my stress or nutritional deficiency but I get really scared everytime I get that sensation. It lasts for 2-3 second and is kind of like muscle tic and twitch. I recently had typhoid and got my CBC done and saw that my TLC was 11,200. What do I do?
