i would assume bursitis the problem as well. must keep in mind that RA not only effects the body's joints...but also the surrounding tissues of the joints.
the bursa is the sac in the connective tissue surroundong the joint; the bursa has synovia (joint fluid) as well.
being in bed is good for now because rest & immobilization are the 1st steps of treating bursitis.
now...is the bursitis in your hips? you had an injection directly into the joint cavity correct? did you get one side or both done?
key is to reduce inflammation at this point via NSAIDs if allowed or RX'd; rest; pressure relief by using a pillow/conform cushion under the tailbone to "lift" hips and relieve pressure; corticosteroids/prednisone; analgesia if RX'd; ice; heat; hydrotherapy and PT if needed.
once the severe & acute pain passes it's important to ambulate to avoid the likelihood of adhesions of the affected bursae area.
it's common to get this from RA. FMS can add to the discomfort of course, but the underlying etiology (bursopathy) and disease at root would be the RA.
i get bursitis of the shoulders and it's torture! constant ice and need a sling.
one can develop chronic bursitis thus surgery is an intervention.
it would be a great help to not only do these prescribed exercises to stretch the muscles NOW but always afterwards as well.
core strength (Pilates and abdominal work) will keep everything pulled in tight in the middle and align the pelvis correctly. the hamstrings and quadriceps need condition too to keep the hips strong. everything in order to keep that center of gravity at it's best will help to avoid future exacerbations.
personally, mine gets aggrevated when i get into the situation of overuse of the shoulder joints. so knowing your personal limits is important.
does the Darvocet help you with your pain? if not...get a hold on your doc before the weekend comes! don't wanna get stuck in pain.
rest well & take care,
