What are the different types of tendonitis?

NSAIDs and rest. Nonsteroidal anti-inflammatories such as Ibuprofen and rest. Once you return to activity, gentle stretching exercises are important. Steroid injections are a bad idea as they can weaken the tendon, possibly leading to more serious problems, such as tendon rupture.
Severity. Mild moderate and severe as the tendon inflammation worsens. Microtears that get larger and more swollen with time becoming chronic called tendonosis as it swells and thickens.
