Hi, My mother is having excessive pain in her right side starting from right breast - back and front till her stomach. She also complains excessively about gas problems and digestion. She vomits usually as and when she has food especially breakfast. Few days she complained of having headache and could not sleep without taking a medicine. We are not able to judge what is this condition and which specialist we should choose to get her checked. Also what all tests could be done or full body check up is recommended? Please assist on priority
