Sore fingers again

Think the fingers on my left hand have been stiff for more than a week now. They hurt and think the fingers are a little puffy. All to do with the swelling and lymph problems caused from the radiation I had. Not a good sign I don't think but seeing The Lymph Lady on Monday so she should be able to sort it out and tell me if it's worth worrying about, Well, how much I should worry.
