1st thing I would suggest is taking warm baths. It helps alot when your sore all over. I also like to add "detoxifying bath salts" and/or some type of aromatherapy to the bath. This also helps the mind to relax ...possibly help with the perception or tolerance of pain. Also certain aromatherapy can perk you up if you need that.  When my energy is low due to pain, I like using uplifting scents like Peppermint.   Next I would recommend massage. Especially if you can have this done after a warm bath or sitting in a hottub. Alot of spas have day passes to use their hottub or saunas. Of Course muscle relaxers can help this along as well.   Followup with getting extra sleep because your body has been fighting the pain/flare, so to lessen the severity or duration of the flare more rest will help.   Keep your joints covered or warm. I notice my joints feel better or don't get as bad if I wear stuff like socks, gloves in colder weather. I use a topical prescription gel, Solaraze, that works well on the joints to reduce inflammation/pain.   If nothing works & the flare is hanging on, I temporarily go on steroids to stop it dead in it's tracks. And if the pain is intense don't hesitate to use pain medication. I have learned the hard way that by not taking something soon enough or when the pain was actually less intense, my pain quickly has turned into a freight train running outta control. Then it really gets hard to keep it under control. Listen to your body.   Lastly, I would say to occupy your mind as much as possible. This helps to keep your focus OFF the pain. At night, I enjoy using relaxation music to help me sleep. I focus on the music, prayer, meditation & find that it keeps my mind from wandering.   Hope these tips help. Healing, Love,  & Understanding go out to you.
