Yes. What an annoying thing. From like two weeks ago I've been feeling this pain in my right forearm, but just when I apply some force i.e. lifting my bass with just my right arm. Pain isn't new to me. In fact, I think that one of the goals when practicing bass should be similar to the ones who pump iron or have a physical training routine. (Well managed) pain is a sign of progress. I mean, if I feel that pain is really big, I stop, take a break and start again when I feel fine, so I'm used to that. Also, I have experienced similar pains in my left forearm when I have gigs with my electric upright after a long time of not playing it (my gigs are usually 5 hours long), but it disappears after a couple of days. But again, this pain comes from like two weeks ago, so I went to the doctor and that was the diagnosis: Lateral epicondylitis, a.k.a. Tennis elbow. He prescribed me Acetaminophen and Methocarbamol plus five therapies. Got the first this afternoon. This woman cleverly located the exact spot of the spasm and made me see the stars . The thing is: I don't know if this happened because of playing "The Trooper" with two fingers so much these days (I'm having kinda "Maiden Fever" after so many years of not listening to them) or because of my PC's mouse. This pisses me off!
