You can pour hot (warm) water in that area to reduce the inflammation. If you have pain in the distal joints ie. Wrist, fingers, ankle, toes then you can wear either elbow brace or wrist brace which will help you to feel warm and very protective.
And also immerse the distal joints in the hot water tub which will help you to reduce the pain.
Consult the near by physiotherapy clinic
and also consult a general physician
to check with your ESR
levels to check whether you have inflammation.
