Hello sir/mam My question is one of my friends mother is suffering from severe headache and pain in right leg with breathing problem. She is unable to breathe at several time in a day. My friend says she feels like minor attacks in breathing. She consulted many doctors and has done stress tests and ecg and thyroid tests also all came normal. Everyone says its due to some tensn but her mother says she do not have any tension and remains relax and cool. So please help us to find us whats the problem with her health as soon as possible and also let us know what kind of tests we can do so that we can know the problem.. Thank you.
