Thanks to All of you for responding. I am relieved to know where the headaches are coming from, but confused about why after 18 years this is happening. But I think I'm lucky it hasn't happened sooner. My rsd had been controlled by meds and keeping active. I suppose the older I get more effects of rsd will be showing up. Thanks again I really appreciate the feedback I get from you guys.

And Bram, you did make me smile.
