My experience with it also is from racquet sports. I suffered for about 2 years and stubbornly played through it. My logic was to not quit what I enjoy while still aggravating it in the more mundane tasks of life that I can't quit so easily. Besides when I tried to quit sports I ate more and got more irritable to be around.
I received advice from many sources. My advice is do all of the above. Disclosure: I am not a trained professional, just passing along what I think I've learned.
1) Ice it after use like you would a badly sprained ankle. I was told it is a similar injury to a sprain although mine was mostly in the upper forearm more than in the joint. Make ice by filling paper Dixie cups in the freezer. Then break the cup to give an ice massage, pressing the cold past the skin deep into the tissue areas that hurt.
2) Rest, then rest and stretch carefully, then rest and stretch and strengthen carefully. As you come back, try for lower impact and shorter periods of time. Stop at the first sign of trouble if you can. With rest alone, the pain subsided for me and I felt healed, but the partial healing was brittle and re-injured instantly on the next impact.
3) Anti-inflammatories: People recommended ibuprofen which I take for other achs and pains, but for me nothing alleviated this pain. Then from two different sources I received advice to take low levels of anti-inflammatories continuously over a period of time. One was from an MD, but not of this specialty, and the other was from an athlete I thought least likely to put these poisons in his systems. This was the remedy that seemed to work. Run it past your trusted medical advisers first as I assume these can be bad for stomach, liver and kidneys. I took a fraction of maximum dosage several times a day - something like 1 (or even 1/2) tablet ibuprofen at a time instead of 2 as over-the counter might suggest or 4 like pharmaceutical strength, and 1 Alleve (or a half) over night - longer lasting. I don't remember for how long but the plan was something like 3 weeks, not completely continuous because I feared the other damages, but often. If you try this, make sure you keep up the other therapies, ice, rest, stretch and very carefully strengthen.
4) 'Elbow brace': The only that works in my experience is this, go here
http://banditelbowbrace.com/ You can buy it in a large tennis store. Basically it absorbs the shock before it goes into the elbow or protects whatever areas in the forearm/elbow that you choose. You tighten down two pads but still allow blood flow. Don't bother with the other styles IMO especially if tightening hard cuts off the flow and most don't really absorb the shock. Search the words 'bandit elbow brace' in google to get competitive prices online. I use the white one and continue to use it for prevention. The black one includes magnets for increasing blood flow. Costs more and I haven't tried it. I don't know about those claims. If you are serious and willing to spend the money, buy 2 of each. Maybe try the magnets without tightening for treatments when not training or competing. I know chiropractors have treatments that stimulate blood flow for healing tennis elbow or at least to make you feel good enough to keep you coming back. I think they use ultrasound(?). For hockey I wear the elbow brace under the protective pads and for outdoor sports in colder seasons I wear it under the clothing.
Good luck and keep us posted.
