Symptoms of Peripheral neuropathy. Pain.

I took covishield vaccine abt a month back and after 8-10 days started getting tingling and burning sensation in left leg and it increased and spread to left arm and right arm,legs, usually happens at night. Consulted general physician and neurologist who asked me to get basic checkups done. My hb1ac is 5.7%, average glucose at 117mg/dl, total cholesterol at 246mg/dl ,uric acid at 8.2mg/dl and tsh at 1.48. I am vitamin d deficient at 4.2ng/dl and b12 is normal at 386pg/dl. No habits of smoking or drinking. Even nerve conduction and enmg report showed everything is normal. Now I am not sure what is the diagnosis. Can vaccine be the culprit as it started after that. Please help! I am clueless and in severe pain and burning oly Matilda forte is helping relieve pain.
