Started developing this red line bruise on the thumb, on the side that is opposite of the thumb nail. The red line seems to be the same shape as the top of the thumb and it goes across. The bruise doesn't seem to hurt but it does gets worse the more I bowl and turning yellowish after a few days.
Recently just had this problem with a ball that is drilled with a new driller that I go to now. Not sure if this is caused by insufficient bevel around the thumbhole or from the tape(s) inside the hole....Anyone had this problem ?
