Hi, I think you should discuss this pain with your Doctor. Since your surgery is so recent, the pain could be related to your surgery. Another possibility is a bladder infection.
What you are describing sounds a lot like a bladder spasm. This can be very painful. Adhesions can start to form as a person heals from surgery, but many people do not form them. I think you should be checked for other possibilities first, so your best bet is to call your surgeon. Hope you feel better soon and good luck............Jeanne
