<s>[INST] Last evening while turning my body in bed I suddenly felt intense pain on my left side in the lower abdominal area. It has continued today. Iam able to walk etc, but when I sneeze or move suddenly to reposition myself in a chair I feel a deep pain in the lower left abdomen. What could this be? [/INST] hi,Thanks for providing the brief history of youSince you mentioned the mechanism of injury i feel it should be just a muscle spasm. for which you can use the hot water fermentation and once the pain level comes down you can proceed to do some core strengthening exercises and spine strengthening too. Be slow in performing exercises. Within a week the pain also should be down and the muscles will start getting the strength as you keep on continuing the exercises and avoid any future symptoms.In case, with in 72 hours of the pain does not reduce, getting checked by a physician and undergoing an abdominal scan is not harmful. If any systemic illness is there, that can be easily found out. Or else in most cases it is just gastritis and muscle spasm.Always, Never to ignore the smallest injury. Prevention is better than cure.feel free for any more queriesRegardsJay Indravadan Patel </s>
