Lateral epicon/DMSO
DMSO was big in the 70's when I first heard of it. As far as I am concerned the jury is still out on this stuff. I know it will take into the skin waterever is there when you apply it, but as far as a treatment to cure and/or relieve..I just cannot tell.
The sides are an objectionable smell on your breath and body odor that is equally bad.
Obviously the best treatment of tennis elbow (tendonitis) is rest. HA!! That's not an option? If you do not rest, this may not go away. The brace is excellent. Ice, oral anti-inflammatories, ultra sound, micro current, maybe even some acupuncture will help, but these done in the abscence of rest are like walking down an "up" escalator and you may be throwing away good cash. The injection of cortisone or celestone is an option, but should be done with great care. Not to be done often as it forms crystals along the tendon and surrounding soft tissues that weaken them and cause the risk of rupture at a later date. I know one doc I discuss this with and depending on the site he insists that celestone (a more mild cortisone) is harmless and he injects himself every time he plays golf.Others refuse to inject an athlete. Somehwere in between is probaly the truth. Given all that....if you inject, I would surely rest for a few days/weeks to be rid of it.
There is a small chance that an avulsion fracture could happen at the site. This means that the tendon actually pulls of a small piece of bone rather than rupture, so you are looking at healing bone rather than tendon. This is rather rare and might need more invasive care.
The worst thing to hear from anyone is that you need rest. But it's the best medicine. What is better, suffering for two years with an injury that will not leave, or 2-3 weeks of rest and going full blast again?
Personal call.
