My mother suffers from a head and neck ache which generally repeats in 2 or 3 days. Whenever this happens, her eyes become watery and on massaging the head and neck, she burps. She says that the more she burps after massaging the more she feels relieved of the ache. She feels it is due to gas problem. But when she has a head or neck ache she doesn't feel pain in her stomach. She has one more problem. She releases gastric (flatulence) with loud sound and there is no smell associated with it. Sometimes she gets stomach pain (then there is no headache or neck ache). Her bp gets low and she becomes lethargic. Doctor in locality will give some gastric relieving injection. I don't know what is the problem. Doctors would advice a gastric prescription but her problem won't go away. She is suffering from this from 10 years.
