Occasionally I feel mild tingling sensation in the nerves on my entire left side of the body. Also twice it has happened that I was sleeping (on the left side) and woke up with severe tingling sensation which subsided after a while. On one such occasion I got several basic tests done including CBC,
LFT, ECG, Blood
sugar,
TSH but all were normal. I suffer from acidity related issues from time to time.
Please advise.
