Hey Kiwidave,
Nasty injury. had the same to the point where I could not even flip a light switch without pain. I started by seeing the GP who told me to stop kiting. This guy studied all that time to come up with the stupidest thing I ever heard!! Stopped for 2 months anyway. then I couldn't stand it anymore and found kiting gave me a bit of relief actually. That made me think.
In my case my desk was to high so I had to lift my arm up and turn my elbows out. that put tension on them all the time and was the cause of the injury. Just saying: it could be something else too. Give this some serious thought. If you have a desk job like me you may do this without realizing. Search the net for ergonomics, desk, sitting position etc. so you know what is ideal and compare it to what your set up is and also what bad habits you may have. (bar pressure is a factor to consider seriously though)
If you recently started supping that may have pushed you over the edge???
Solution for me:
stretching and strengthening. I will try and explain a few stretches (in case you're not doing these already).
Hold each stretch 20-30 seconds. make sets of 3 for each stretch and do it a few times a day if you can.
1)raise your arm in front of you to about horizontal. point your fingers up and pull them towards you with your other hand.
2) same arm position but now point your finger downwards and pull them towards you with the other hand.
3) put your hand palms together against you chest, fingers pointing to your chin. now move them downwards, keep your palms together. this stretches the underside of your arms. I also moved them (in the low position) slightly left and right. that brought the stretch all the way into my elbow.
4) put you arm sideways, horizontal, fingers pointing backwards and put your hand flat against a wall. now twist your body until you get a good stretch. try some different angles and you will feel you get some stretch in your biceps as well.
5) I also bought a massager. Somehow the Missus is tired of giving me a massage. Funny how that look saying ' you and all your stupid sports' never seems to tire her out??!! Anyway, back on topic; From your name I recon you're in NZ as I am. I bought this one from trade me years ago. Still working. just have to replace the power cord every few years
www.trademe.co.nz/health-beauty/massage/massagers/other/auction-925599410.htm6) They also made me massage the sore spot and also put a lot of pressure on it by just pushing your finger on the sore spot.
I also started working weights again. Just a bench with a few dumbells did the job for me. Saw a physio and an osteopath. the last one put me through a few days of pain after the treatment but cured me and it hasn't come back!! The osteo also sorted a few stuck and twisted bits and pieces in my back. That seemed to help a bit as well. All in all it took me a year to get rid of it.
I kited wearing those tennis elbow velcros around my forearm for a while as well.
****, what a misery now that I write it all down like this.
My advise would be: start those stretches and see a physio asap. They will be able to tell you what exactly it is and your do's and don'ts. If the sore spot feels warm then it is inflamed. Voltaren gel or the pills do wonders with that in just a few days.
Hope that any of this will help you on your way to recovery.
good luck.
cheers
