Thumb Nail Trouble
Posted: February 8th, 2018, 3:09 pm
I need some advice on some trouble I am having with my thumb. Each time I bowl my thumb nail goes blue and get redness just below the nail. The problem seems to get worse if I have a week off bowling which is strange and better when I bowl more.
My pro shop guy has no idea but said my span is correct. My span is 4 1/2 full span and I have 1/8 rev and 0 pitch on my thumb
Any advice would be appreciated.
