How long does it take for abdominis rectus muscle tear to heal?

Thank you very much for sharing your concerns with us.The initial treatment for chronic abdominis muscle tear is conservative: to have relative rest, avoiding any activity that increase intra-abdominal pressure, that's means avoid efforts like carry much weight or becoming constipated.Also, you have to take anti-inflammatory pills and painkillers for some period.You should get another MRI four months after this conservative treatment and, if the problem still persists, we must consider a surgical option.Kind regards, Dr. Emmanuel Mallol Cotes.-            

A torn rectus muscle will probably be actively healing for six months or longer. It should be protected during this convalescence. Discomfort will be a guide to the speed of the healing process.

Thank you for your question. Unfortunately you seem to have a complicated past surgical history with your abdomen and hernia history. It is difficult to really answer your question without knowing exactly what is taking place, and that requires a thorough review of your MRI and a physical exam.  The reason is that without knowing the extent and location of the "chronic abdominis muscle tear" it is difficult to make a treatment recommendation. I am not sure what type of physician that you saw, but you may want to have second opinions with a general surgeon and/or plastic surgeon.  Best wishes
