i sometimes wake up with a numb thumb and first 2 fingers in both hands. It seems to be when I wake up with bent wrists. Not sure why this is happening but it's a position I find I wake up in quite a lot. The feeling goes off after a few minutes but I still feel a tightness in my wrists for an hour or more afterwards. I don't play bass for hours, more like 30-40 mins every other night at the moment. I think it maybe more related to holding my mobile phone too much, reading it in bed before going to sleep etc. So thought I'd check if anyone else gets this and whether it has affected their playing? Like I say, I don't think the playing is the cause as it predates me picking up the bass. I think it's more sleeping position, mobile phone, computer keyboard/mouse or years of gripping a racing bike handlebar. The other thing that has come on recently though is an ache around the knuckles on my plucking hand. This affects first and second fingers and yes, I play finger style. Worried it may be arthritis as I've no recollection of banging it recently. I'm 51 next month and been playing around 15 months.
