I Am A Male,70 Yrs Old That Was Diagnosed In

I am a male,70 yrs old that was diagnosed in 1999 w/ Bi-lateral CTS.After 4 surgeries I have permanent nerve damage to both hands. Six yrs ago I was diagnosed w/end stage osteoarthritis in both shoulders & underwent shoulder replacement surgery. Now I find that I have what appears to be small growths or bumps on the outside of both feet a few inches below both small toes. Is this again another form of arthritis? I wear a size 12-5E and for over 25 yrs worked as an Industrial Scale Engineer,testing scales by repeatedly lifting on again & off again 50 lb test weights to 500 lbs capacities and pulling around 650 # carts ! please note. I do have a regular GP plus specialists that I already see for my CTS. My immediate family is in the medical profession. I can touch base with my regular Doctor when I see her next. Sorry for the bother
