Several years ago, I had a bad UTI which I couldn't get rid of so went to the doc and was put on Cipro, which attacked my Achilles' tendons on both ankles. The pain was excruciating. Docs gave me a muscle relaxant, which did nothing. As a last resort, I had my hubby rub castor oil on my ankles several times a day. Took pain away within one day...haven't had a problem since...
I might add that I since found out there was a class-action suit against the makers of Cipro as it was causing tendon ruptures in many people. Guess I was lucky and the Castor oil healed it on me. I use it for many things, including the packs, and take it orally occasionally, but only organic cold-pressed and hexane-free.
