Hi Dale
Welcome to the forum! Sorry I am unable to help on this; it's something I have fortunately not experienced. Possibly worth a word with your GP initially who might then refer you back to Rheumatology. Symptoms such as this are always worth following up in case its significant of other problems or even suggestive of an adjustment in medication. Hope it is sorted for you soon!
The forum is a great place to be with lots of friendly members who are able to offer support and advice based on their own experiences of life with RA. I'm Lyn, by the way, had RA for 22 years and run the gamut of medication and various surgical procedures. Currently on Enbrel, Methotrexate and a bagful of other stuff to keep things ticking over! Married, four kids, and live in Thornton Cleveleys in Lancashire.
Look forward to getting to know you Dale
