Alright, so I may just be worrying too, too much but hear me out. Firstly, I'm not much of a fingerstyle player, because till now I mostly played songs that didn't require the use of fingers, or the original bassist had used a pick too. But yes, I did practise my fingerstyle technique, hoping to gradually improve it so that I could start with some Maiden. So yesterday, I was playing the Clairvoyant repeatedly, about 4 times. Then I switched to The Number of the Beast. I had barely been playing for about 2 and a half hours, when I noticed a pain in the below mentioned area. The area is as follows: Look at the skin between the middle finger and the ring finger (on the back of the hand). Now slowly run your finger south from that area, till JUST south of the knuckles. That's where I observed the pain. It was a sharp pain, that went away as soon as I stopped playing. For a newbie to playing Steve Harris basslines, I expected it to be hard on the plucking hand, as these basslines usually involve speed and stamina. I stopped playing right then, and now about 14 hours later (which includes 10 of sleep) the situation is still the same. I looked up Carpal Tunnel Syndrome on the net, and searched for images of affected areas, and found that the area of pain seems to come under the affected areas.. Please, please help me out here. Is it really CTS? I only started playing about a year ago, and I'm 15 (if that makes a difference at all).
