Tendonitis is characterized by soreness and swelling around a joint and tendon. It often occurs “when some harsh or violent strain occurs on a tendon, or when someone [repeatedly] moves their body in a way that it is not used to,” says Brynna Connor, MD, of NorthWestPharmacy.com.
If your pain remains longer than several weeks, you should see a doctor. Otherwise, over-the-counter (OTC) treatments may be sufficient. Some of the best OTC treatments include NSAIDs, topical anti-inflammatory gels, ice wraps, compression therapy, heat therapy, and Epsom salt. When picking an OTC treatment, consider active ingredients and cost. NSAIDS, ice packs, and compression therapy braces are generally inexpensive and highly effective.
