What alternative medicines could I take for my tendinitis?

Tumeric and traumeel. Tumeric and traumeel can be used as anti-inflammatories orally. Traumeel or arnica gel can be used topically. Apitherapy, prolotherapy and massage (especially art) can be used to successfully treat tendinitis as well.
Antii-nflammatories. Over the counter versions work well, if you take them with food. Tylenol (acetaminophen) works for pain but does not cut inflammation.
