Hi, yes I have had it badly about three or four years ago. Very painful and frustrating.
I have to say (touchwood) I haven't had it since.

The things I have found to help it in no particular order are try a magnetic bracelet/necklace I.e. trion:z

This gel keep it in the bag http://www.pcpdirect.co.uk/Pharmacy/Pain-Relief-Topical/771-Voltarol-Emugel-P-50g.html

Or a cortisone injection seemed to work for a while then wears off.
Or try one of these http://www.physioroom.com/product/Aircast_Pneumatic_Armband/3074/37869.html

All seemed to help would probably recommend the armband or voltoral gel..

Hope this helps cheers.

i had golfers elbow a few years ago and went to a physiotherapist about it. the exercise i was given involves a weighted bucket up to about 3/4 full of sand. bend over to pick up the bucket but keep the arm holding the bucket straight. take the weight by taking the strain of raising the bucket by pushing with the free arm on, say, a chair back. you should now be in a slightly bent over position and the bucket swinging free. turn the bucket alternately clockwise and ant-clockwise about 20 times and do this about twice a day. start off with a light weight of sand in the bucket and gradually increase the amount of sand [or earth] until the bucket gets up to the 3/4 full mark. you should not at any stage get any pain. if you do, then do the exercise less vigorously or decrease the weight in the bucket. not only will this fix the golfer's elbow, but it will increase the strength in your wrist and the distance you hit the ball. when your golfer's elbow is cured do the exercise occasionally to keep the problem away.
this worked for me, so i hope it works for you.
I would always avoid cortisone and surgery wherever possible.

I suffer from this also, exacerbated by tennis and gardening. I am trying a course of accupuncture and initial results very encouraging (on my bad back as well). Seems to speed up the healing process, so maybe give it a go before trying surgery?

If you don't drop your elbow - relax the arm while swinging can result in this . Magnetic wrist bands help as does aguapuncher I am told .But get your swing sorted out by a pro around your age .
