I had my sleeve surgery on April 26, 2019. Today is the 30th. Everything has been great since surgery except for one thing!! Periodically I have spasms/cramps in my stomach. It's not my incisions but inside. They only happen for a few seconds and then they go away. Sometimes they come back every few minutes. And other times it will be a few hours. Why do I feel these pains? They are getting really annoying!! Any advice would be awesome!
