Hey guys and gals... Anyone here have this sharp pain that totally keeps you from hitting any kind of backhand? I get this all the time, and only after serving will the pain sometimes go away. Makes me and my partner's nuts when I try to warm up with this weird pain, but usually 1/4 thru the set, the pain goes away and the topspin backhand comes back. Not willing to go back to 2HBH, mainly because I'm 60 and not too quick with the feet or the reach. Thanks.
