Bill,I have a bottle of Ibuprofen.It goes everywhere with me.When things start hurting,while trapping or even before.Its Ibu time.
Keeping the hands covered at all times ,with gloves or gauntlets also helps.
I remember when I was 35 ,started playing ball again after a 14 year layoff.Finally retired when I was 49,but after getting glasses Iplayed last year.Hit 600 again so I knew the glasses really helped me see the ball,just wish I could run like I could in my 30s.
Bill talk to your doc about the arthritis,he may be able to steer you onto something better.
