A few years back I had a nuclear bone scan, the dr wanted to see if a cancerous tumor on my prostate had spread before surgery. After the scan I asked the technician how I looked. She told me that's for my doctors to discuss not her but, she winked and said the only thing I'd be concerned about is the arthritis on the base of my large right toe where it meets the foot! Somewhat relieved, I thanked her and told her I had lousy pop-up form over my lifetime of surfing, i.e., I always seemed to drag my right foot with that 'nuckle' in contact with the board. From the late 1950s until my 65th turned the 'sore toe' into arthritis. A dab of Voltaren Gel on the nuckle and I'm good to go!
