I am a 27 yr old female who has been dealing with this problem for 4 yrs. I am seen 2 different neurologist (1 when the symptoms 1st began and one a few months ago) who have no idea what is causing the problems. It began when I was 24 and started out as numbness/tingling sensation in my left foot. I went to my PCP who ordered a non-contrast MRI due to my family history of MS. It was negative and by the time I got the results, the sensation had spread up my left leg. He referred me to a neurologist who ran blood work, ordered cervical and lumbar non-contrast MRIs, and a nerve conduction study on that leg. All results were normal except for a B-12 deficiency. By this time, I was the sensation had spread up my left arm and to the left side of my face. I was also very tired all the time. I was given B-12 shots which helped and my symptoms went away. They returned about 6 mos later, and I was given more B-12 shots. They resolved again. About 1 yr later they began again. The sensations became almost painful and kept me up at night. I saw my PCP again, and he took me off Paxil. He thought it might be a side effect of the meds. After weaning off Paxil, the symptoms resolved again. The sensations have stayed mainly in my left foot and leg when they return. I went symptom free again until this past fall. I returned once again to my PCP. He ordered blood work to check my vitamin levels and this time I had a vitamin D deficiency. I was given supplements and referred to another neurologist (b/c I did not care for the 1st neurologist I saw). She ordered blood work checking for autoimmune disorders and a brain/cervical MRI w/ contrast. All were normal. She is treating me for nerve pain. The medication she gave me I cannot take due to the side effects. I go back to see her this month. I The symptoms just went again, but now I have developed a rash on my left arm. It does not itch nor does it go away with allergy meds. I noticed it about 1 1/2 mos ago. The symptoms appear for a couple of months, then go away. They interrupt my life because it effects my sleep and the symptoms are annoying. I am just looking for a possible direction to finding a diagnosis.
Here is some other medical background information. I have not had children yet. I have asthma and lots of skin allergies. I am highly allergic to shellfish, iodine, and contrast w/ iodine. I do have a lot of UTI's and have been diagnosed with bladder cystitis. I have also recently been recently diagnosed with acid reflux. Other than that I am pretty healthy. I do catch colds easily, bruise easily, and heal slowly. I do have anxiety. However, I am in graduate school pursuing a PH.D. Thank you in advance for any help.
