Can tendinitis heal itself?

Tendon sheath inflammation is caused by

overuse, strain, or injury of tendons in the tendon sheath. For milder patients, the body's natural healing mechanisms are sufficient to deal with inflammation and repair damaged tissue. With proper rest, patients generally can heal themselves. For more severe patients, these problems may not be completely resolved by their own repair mechanisms. In this case, they generally do not heal themselves. Medical intervention is needed to accelerate the healing process or repair damaged structures.
