I'm currently training for the NYC marathon, and after my long runs it helps my legs to take a brief ice bath. However, after the ice bath, I will soak in warm water. That's when I develop a strange and powerful arthritic-type pain in my finger joints, mostly in my left hand. This is not the "stinging & swelling" sensation you get when you stick your cold hand under hot water. That's different. This pain is like the worst rheumatoid arthritis pain you can imagine!
What function of the body causes this?? I assume its the lactic acid leaving my legs and entering the blood stream, and perhaps accumulating around my finger joints. Its ironic that its mostly in my left hand, which is closest to the heart. The pain hits immediately upon turning on the warm water and last for about 3 minutes. Also, are then any practical measures I can take to prevent this?
Just curious. Thanks! Russ
