I was having trouble with that this year for the first time. I guess I'm middle aged now so I should expect such things.
You can try an anti-inflammatory if you can take them like naproxin.
Mine was so bad that I eventually had to go to the doctor and he gave me a shot of cortizone I think and something else. it still hurt for a month after that though. I blame all the cleaning i did on my xmas vacation!
you can also try ice pack (frozen peas work well) or sometimes epson salt soaks but it is sort of hard to soak your elbow
