i bought my own bass and had been practicing for more than half a year now. the problem is i feel that the bridge is a little too high, and its been causing some pain to my wrist, i get something as if my veins had broken. in pain, whenever i put push my left hand flat on a wall or something, i get a very painful sensation, shud i change the bridge or mould it? For the right hand, (i use the french bow), i always somehow slip my thumb from curving outwards into curving inwards. i noticed the 'thing' where i put my thumb on is really rounded, probably thats the problem, shud i change bow or was my method wrong?
