I suffered from golf for two years with bilateral epicondylitis before
being diagnosed with psoriatic Enthesitis. I never had radiating pain
of an entire arm.
Consider getting reexamined and ask to check for nerve entrapment.
I was able to golf by using ice packs before and afterwards for two days.
Elbow freezer gel packs are available online for convenience.
The strap for tennis elbow applied above or below my elbow for golf felt helpful. I used voltaren gel topical regularly.
I also took NSAIDS before and after. Ultrasound can be used to visualize
tendon inflammation. I golf without trouble now on Humira controlling
psoriatic arthritis.
