If you are taking medication to treat your arthritis symptoms, avoid sun exposure. People with arthritis are actually a lot more susceptible to a lot of conditions caused by the burning sun in the sky, especially Lupus. Do what you can to avoid sun exposure, from wearing clothing that protects from the sun to sunscreen, no matter what the season is. Even during the winter, you are absorbing a great deal of the sun's rays.
Let your family and friends know that you have issues with arthritis. If your loved ones are made aware of what you are dealing with, they will better understand your needs and can in turn offer helpful support and aid. If you recognize your pain and feel stiff, your family should understand.
