I used local physiotherapist to ‘cure’ mine. 3 yrs ago was my right elbow, this year my left.
Pain started in early May, early June first physio, then kept going with bi weekly ish through June and July. Was caused by carrying too many heavy things repeatedly at cub camp.
Early on the strap definitely helped to reduce the pain (esp the ‘ache’ at weird times of the day)
Really intensive physio massage (i.e. bloody agony!) and ultrasound at my appts, and several different targeted exercises at home. Noticed by end of August it had mostly gone. Now 99% fine and not doing any thing specific for it.
acupuncture did not make any difference for me, but N=2 elbows of above mentioned intense physio massage, ultrasound + exercises eventually worked.
So 5 months roughly from onset to gone. It’s a tough bugger to shift, but being consistent rally helped.
