Question

Tendinitis pain: Should I apply ice or heat?

My husband has tendinitis, and his doctor recommended warm compresses for pain. Our neighbor suggested ice instead. Which is better?

Answer

from Edward R. Laskowski, M.D.

If tendinitis is of recent onset, ice may be a better choice for reducing pain and inflammation. Ice causes narrowing of blood vessels (vasoconstriction) and is helpful in reducing swelling. Reducing swelling also helps reduce the level of some inflammatory substances that can be produced with tissue injury. If tendinitis is long-standing, either heat or ice can help to improve pain.

In general, a new injury to a muscle or joint that causes swelling and pain is best treated with ice. Heat promotes opening (vasodilation) of the blood vessels. This can increase blood flow to an area of chronic injury to promote healing.

Applying heat to a long-term injury to promote blood flow before exercise and ice to the area to reduce swelling after exercise also may be an effective strategy — although there's no strong scientific evidence to support this pattern of use.
