The throbbing is from swelling in the joint space. Elevate above heart level and use a gel ice pack to mold to the top of your foot.

I soak my feet in hot Epson salt water always helps me

I hadn't heard of prednisone until I started on this site. Unless its known by another name here in the uk . My feet and wrists tend to be the worst to flare .but since I've been off work I haven't been bad at all . So I've worked it out after almost 40years of pain I'm allergic to work lol xxx hope you find some relief soon darling xx

Heating pads if heat works well for you, otherwise icing. It's painful but do try to stretch if you can - I really find stretching overall helps so much. Prednisone for short term relief, too. Hope you find relief soon!

I too use Epsom salt.I use the one with Lavender it help to relax you hope you find something that works for you.
