There is likely something in your everyday life that is hurting you. In my case it was my wallet in my back pocket and the driver’s seat in my car. Find out and get rid of it. Relief is nice, but you know what they say about prevention and cure...JFK
Same situation for me. I've been going with my wallet in my front pants pocket now for several years. I don't care if it does look odd. I just know I don't want to have to endure that pain again.
It took awhile before it didn't flare up on a long long drive anymore, but I haven't had the problem at all for a few years now, so making that change did take care of it.
