What exercise can't i do with tendinitis? should i avoid exercising if i have tendinitis?

Avoid overuse: Tendonitis is most often really a "soft tissue fatigue fracture" the tendon wears out because as we get older than 20 - 30 our tissues heal more slowly. Tennis elbow, shoulder "bursitis" , achilles tendonitis and patellar tendonitis are usually really tendonosis. The failure of micro trauma (usually from overuse) to heal. Rest and gentle eccentric exercises can often resolve symptoms in time.
