How long for my shoulder rotator cuff injury to heal?

Hard to say: I'm sorry, but there is just not enough info to answer this one. Is it a full tear or partial or just tendinitis? Did it develop over time or from one big injury? Have you had surgery? All of these things, as well as patient specific factors, affect healing. The bigger the injury, the longer the healing. A strain can heal quickly (weeks) but a repaired cuff can take 6 months.

Severity dictates: Not all rotator cuff injuries are the same. Important variables that determine time to healing include: size, location and extent of the cuff injury along with the overall health of the injured patient. History of injury, examination findings, and imaging studies (x-ray & mri) allow your treating physician to make a reasonably accurate estimation regarding time to healing with or without surgery.

Rotator cuff: Recover from a rotator cuff injury depends on a lot of variables. Is the injury a compete tear? If yes and surgery is required, recovery can be longer than 6 months. If not a complete tear, recovery may be anywhere from 3 weeks to 3 months.

2-3 months.: Sometimes it can take that long if it's a strain to the rotator cuff. If it's a tear, it may not heal and may require surgery.
