As some of you may know, I'm a come-backer. I started playing again a little over a month ago after about 30 years. I play 4-5 times per week, on average, for about 45 minutes each time. For the past couple of weeks, I've noticed that my lips have been very numb. This numbness lasts for over a day, so it's just not temporary. I presumed this was par for the course; that my chops just need to toughen up. But it hasn't subsided...so just wondering: Is this just par for the course? I just don't remember this sensation occurring 30 years ago (not like I remember much from back then anyhow). TIA.
