AccuWeather has an arthritis index and for today it is 5 or at risk.
The weather is crummy, to put it mildly. It is cool out, damp and drizzly, and just a good day to stay in.
A friend of mine has arthritis and to show that the numbers mean something she is rotating ice packs on the worst areas. The index is accurate and the ice does heap.
The numbers go down Monday and the rest of the week so there is hopefully relief on the way.
It is interesting that a weather forecast can predict things like this. I have found it to be surprisingly accurate in the past as well. It can be a source of hope or "light at the end of the tunnel" at times.
