Hi, This is my second time around playing the fiddle. I started playing again last year and decided that this time was going to be different-regular practice, everyday for at least an hour, develop good technique etc. and apart from a few missed days early on I’m proud to say I’ve stuck to it and am now well in the habit. After a few months I developed a very large calluse on my left hand where my hand rubs the neck. I had one before but it was nothing like this! After a couple of hours playing it gets really sore and I’m forced to stop, which is frustrating if things are going well. Is this something that will stop eventually or is there something I can put on it? Any advice would be welcome.
