I did my post natal massage 5 days after normal delivery. I do not have menses-like cramps initially, but after I did the belly wrap there are painful cramps where I feel that the gas is stucked inside. I couldn't stand straight and my lower back is very painful. I feel like it doesn't seems normal as the pain is quite intense. I did belly wrap for 4 days and there are 6 more sessions to go. Does anyone have the same experience?
