so sorry about all the pain lately

wondering if your husband's cancer is adding stress and that's affecting your body too? i always deny a stress - inflammation connection but who knows?
have you tried ultrasound? i can't remember? when my feet were so awful that i could feel the PF tear when i walked (for me, edema from vioxx was what was exacerbating mine), only two things helped: contrast baths several times a day and ultrasound at the PTs. those things are worth a try to help settle things down if you haven't tried them already.
i know ultrasound may not be helpful for everyone, but for me, as you might remember, its so helpful, i bought my own, after a lot of research and louise's help here in picking one out.
in fact, right now, in a bit of a flare, ribs especially the top one keeps wanting to come out. left upper back / shoulder / neck all involved. every morning and every night my DH has been doing ultrasound on that area. i can't exactly tell you what it does, but its very helpful.
has also always been very helpful for tendon inflammation.
