Others have heard my story. Fisherman's elbow crippled my fishing for a long time 3 yrs ago. Fortunately I have overcome it, but I feel for any angler who has a severe case of fisherman's elbow. AKA: lateral epicondilitis. If not treated correctly it can become extremely debilitating. I tried the cortizon shot route. Yes, felt relief, but after 4 weeks the pain came back. Icing was a daily ritual, however that doesn't help cure it. I took high dosages of anti-inflammatories, which later caused me to have a kidney stone. (That is not fun what so ever!!!) Finally, after a 9 months of battling this issue, I was referred to a Physical Therapist that educated me, treated me extensively, and thank goodness helped me recover. I have since learned what to read the signs and back off or change the techniques that effected me.
Fisherman's elbow is basically an overuse injury. Caused by a few reasons. As it pertains to the fisherman, incorrect repetitive form and/or heavy fishing equipment compounded with time can be a recipe for Fisherman's elbow. Also, weak back, shoulder, bicep and tricep muscles help exacerbate the issue. How to treat it? First off, you have to get the swelling down. Deep tissue massage although extremely uncomfortable helps tremendously. Ultrasound therapy in conjunction with massage therapy may be very beneficial. Finally, a well balanced strength training program will help ensure the issue will not return.
Lastly, proper bio-mechanics. The angler could be holding the rod and reel incorrectly, although to the angler it may appear completely normal. Arm position, how we set the hook, etc can all be culprits. Having others study the way you fish can be very helpful in correcting poor technique.
To the OP, best of luck in dealing with this issue. After experiencing this injury, I can tell you its no laughing matter. If you want additional info or help, you can PM me at any time.
