Sorry to hear that, hope you are on the right track to recovery. My wife's dad used to have that, he took lemongrass tea daily to help get rid of that thing, took a while tho. Not sure whether theres scientific proof on that, actually he consumes all sorts of herbal things thats been recommended to him.
Good that youre reaching out to the elder riders, I wish I had the same moral support then. Hey I just built a proper flatland bike, mix n match of some old and new parts. I juggle between flat n street, just to keep it interesting. Really into Karl Poynter n DeGroot's riding now. Yeah rail riding is a bit too risky as far as injuries are concerned, my case they are mean to the wrist. Haha noo, I dont think theres much I can show you, theres dozens of good tutors on youtube! Honestly I'd nvr tried to upload any vid anywhere, am no good with all these media stuff!
Hey check this out, salute the elders! Watch the diet, bless you!
