when i shoot my recurve normally i dont notice any shock at all, unfortinitally the past two years i have had finger injurys to my bow hand and let me tell you with an injured finger i feel a ton of shock is this a tuning issue or just due to the injury?
I say either or both-you may be able to tune it out even tho your fingers are over sensitive. Increase brace, heavier arrow, different string. Any or all of those should help, make changes one at a time.
Also try taping the injured finger to its neighbor-see if that helps.
I gotta agree with Bjorn try increasing yor brace height.
lots depends on your bow grip ...
do not fully grip the bow's handle. do not use a tight grip. allow only the web and flesh of your bow hand to contact the bow's handle - doesn't matter the style of recurve (or longbow!) handle. this will float the grip and allow minimal contact between your bow hand and the bow's handle. make sure to use at least a 9gpp arrow - 10gpp or more is better.

That's it. It's definitive. Recurves are hand-shocky. Just kidding with you - the simplest answer seems to be that your hand injury is causing your to grip your bow differently than it wants to be gripped.
Similarly with a longbow - a funky grip will yield funky results.
