Yes, I've had it, but for the life of me I don't recall the exact remedy. Seems to me ultimately my chiro (seeing him for a diff reason) did some trigger point or something similar. I DO however recall it that session hurting like a sonofabitch!
My chiro performed a cubital adjustment on me once. I haven't asked for another since!!
There are specific stretching exercises you can do in the acute/minor stage of UNE. Actually, there aren't too many different ways to stretch that region, and these stretches are pretty much the same ones you often perform for condylar tendons when treating tendonitits.
NSAID's can also be effective for milder cases.
I believe the cause of the condition has a major influence over the severity of symptoms. Static elbow pressure such as what happened to me seems to present the mildest and most easily treatable symptoms. UNE resulting from strenuous overuse or inflicted trauma tends to require more drastic means to correct - oftentimes including surgical relocation of the nerve from the affected area. The surgery is only about 76% effective.
