Looking for Diagnosis and Treatment.

I have been suffering from unpleasant leg pain, tingling, burning, heaviness, and weakness since November 2021. These symptoms began suddenly while I was lying down in bed. There is numbness on the left side of my thigh that lasts for 30–60 seconds and then goes away. The symptoms are located on the lateral side of my left leg and spread up to my thigh after 15–20 days. After three months, the same symptoms switched to the lateral side of my right leg and spread to the thigh. Multiple treatments have been done, and now the pain comes and goes. I received the first dose of Covishield on August 21 and second dose in November 21. I did not experience these symptoms before the vaccination and they appeared only afterward the first dose only. I don't have any back pain and no issues walking, sitting and running. 19th July 2022 my Interluken 6, ACE, ESR, COVID antibodies were high now all three are normal but COVID antibodies are still high. Is it after the vaccination effect?
