Hi doctor, my name is Anita, the question I am asking for my husband. From last one month he is feeling very uneasy, suddenly he getting nervous, not take food properly, suddenly his hands getting shaking, after few minutes he will be ok. To go out of house he is scared, we showed to doctor he gave some gas tables. Today after lunch he felt black out, giddiness n felt falling down. We don't know what to do. Please help us. Should I take him immediate to doctor.
