Hello,
Resuturing of the tubes after tubal ligation is not an easy process and is done by surgery. You should discuss the pros and cons with your gynecologist and then get it done.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
