My wife is suffering of faint issue whenever she is in stress. We want to know which specialist we need to consult. Please help us.

Yes sometime

I will suggest to you the best doctors you consult the best orthopedic doctors 

You should see a doctor if your back pain lasts longer than a few weeks, is severe, or is accompanied by symptoms like fever, numbness, or weakness in the legs. Proper treatment is necessary if the pain follows an accident or injury.
