Hello Doctor, I am in very big trouble please help me. My mother is 58 years old and she feels burning sensation in legs, hands and on stomach. We have consulted dermatologist, skin specialist but nothing came in reports. We have already performed urine, blood test, ecg, Blood pressure and so many other test but everything is normal. Now we are in confusion what shall we do so that she can sleep properly. Every night she doesn t sleep well. Can it be related to nervous system disorder? And if yes then what shall be do?
