In reply to lasonj:
The classic test is to stretch your arm out in front of you with the palm facing down and fingers slightly spread. Use your other hand to press gently down on the middle finger and try to stop that moving. If it's tennis elbow it will hurt like hell on the outside of the elbow.
I've had it badly in both arms. The first is virtually pain free all the time now after 18 months and the other nearly recovered after a year. It goes through different phases and at the moment exercise like climbing helps but sudden shocks are still bad.
Someone mention the low blood flow affecting the recovery and this seems to be the key. My consultant quoted a large study comparing the use of anti-inflamatories (including steroid injections and non-steroidals like brufen), acupuncture and a pattern of injections around the site.
This showed the anti-inflamatories only provided interim relief and prolonged the overall recovery times. This was thought to be because it reduced inflamation and blood flow to the area reducing the rate of healing.
Acupuncture showed an improvement over no action but not as much as the pattern of injections. In both cases the treatment was thought to increase trauma in the affected area bringing increased blood flow and increasing the healing rate.
I had previously tried physio and acupuncture with little improvement (although the latter did improve things a bit). My consultant then did the injections which involved injecting many times close to the site of the problem in a stippling pattern. There was nothing more than a local anesthetic in the injection itself. Recovery was very rapid after that.
There are always plenty of anecdotal messages about TE but this guy really seemed to know his stuff and was based on the evidence of a large clinical trial. If he is to be believed then these are the things to do:
1. Complete rest of the affected elbow but maintain your fitness with other exercise.
2. Do not use any anti-inflamatories.
3. Perform the standard strengthening exercises on the arm.
4. Have the stippling injections to speed the recovery time.
5. Don't expect it to clear up quickly even in the best case.
You have my sympathies. It has set back my climbing a great deal but I am now back to where I was before it came on so there is light at the end of the longish tunnel.
