Hi, ! Is this a new symptom you are experiencing? Do you believe these flu-like feelings are related to your RA? Have you discussed what you are experiencing with your doctor?
I know that some of our community members describe their RA feeling like a near-constant case of the flu. I wanted to share this conversation from our forums that might be helpful for you -- https://rheumatoidarthritis.net/forums/flu-symptoms. You are definitely not alone in feeling like this!
But again, just to be safe, if this is a new symptom for you, please contact your physician.
