Hello! A few weeks ago i woke up the day after band rehearsal and both my hands felt really tender, like i'd trapped them slightly in a car door. After a few days the pain calmed down and now the pain has gone in my right hand. I play right handed picking with my fingers by the way. But now, even if i've been playing for a very short ammount of time (10 mins) the knuckles on the index finger of my left (fretting) hand start to hurt again and it almost feels as if it is swallen even though it doesn't look like it is. Has anyone had any experience like this and has anyone got any idea for a remedy?
