Just a few days ago I started to play 5 string sweeps after playing 3 string sweeps for a few weeks and I'm OK (triplets at 160bpm ) but at first I had trouble reaching up to the 19th fret on the A string with my pinky so I tightened my strap to raise the guitar to make it easier, which it did do and I found it alot more comfortable playing other stuff to, but since then I've been getting pains in the back of my left hand (I'm right handed) after playing for about 30 min. Not that I don't get little aches after playing for a while but I haven't hurt this much since my first week of playing where I practiced till my fingertips bled.

Should I lower the guitar back or just take a rest for a couple of days seeing as I usually play about 5 hours a day during the holidays and about 2-3 hours when schools on. I've only gone about 5 days all up with out playing since I first got my guitar too (a year coming up this week). Or should I just push through the pain and keep playing?
