Since 4-5 days my mother is experiencing frequent sweat followed by ant sensation in her hands as well as in legs. This has happened earlier also at that time we had consulted to Neurologist. We did EMG/NCS test whose reports were normal. She is taking medicine for thyroid also but in her last blood test which was done 2-3 months back, it was normal. Can you please tell me what exactly be the problem or cause behind this symptoms? Is it due to perimenopause because her periods are irregular and comes alternate month or even with a gap of 2 months. What exactly now we have to do?
