I've just joined a new band, and we're touring in January, which means I have a list of songs to learn as long as my arm. I've been practising about 4 to 5 hours a day so I can get this done to make the transition into this band smooth, but the last few nights I've been woken up by a searing white hot pain in my left arm, with numbness and pins and needles. I'm fine when I'm playing but if I just lie down and try to rest the pain starts and won't go, even if I shake my arm and try to let the blood flow back. I know I'm overdoing it a bit, but I have so much to do, and this band is funky, with very bass heavy songs...I have a lot to play. Anyone had this before? I know the answer is to slow down a bit but I can't! I have no time.
