So a couple monthes have passed since i hurt my hand playing guitar. What i was doing was a very long reaach across the fretboard and i hadd a quick jolt of pain on the back side of my hand. I have tolerated it thus far but now its getting to the point where when i play for about an hour it will really start to get aggravated and it makes it hard to play. Any suggestions to what i can do to help this without going to the doctor.( I really want to keep up with my playing)
