Due to certain immdediate pose/posture (like tried to pull the seat belt while seating in driving seat, or during sudden coughing), i feel sudden ache/cramps in stomach. It can be anywhere left, right or center. Mostly, it will be short lived for 1 - 10mins. The pain cause due to this terrific, as i have to stop my movement for sometime, feels like getting laid down immdediately.I try to breathe properly and stay calm to avoid/overcome the pain. I am aged 33, Male, Wt: 105kg, Ht: 5.6 ft, Body type: Overweight/ Obeese. Kindly, advice on the this issue- is this because of gas problem or something else very serious?
