OMG ! I am going through this exact same thing right now & have been for about a month so far. I have been to a foot & ankle surgeon who has put a boot on one foot because of severe achille's tendonitis. Both feet are so swollen, my toes look like little cigar stubs. I can't flex my feet sideways at my ankles because of the level 9 pain in them when I do. Also when I try to bend my ankles, my heels, ankles & soles feel like they are wrapped up in elastic bandages that are too tight. The shin & calf of both legs above the ankles feel like they are on fire & can't be touched because they are so tender. They itch like crazy & feel like bugs are running up & down my legs & across my feet. Guess who is NOT wearing the boot to stabilize the achille's tendon? When I wear it, the pressure on the tender skin above the ankle to the mid calf is so bad, I stood in Walmart yesterday crying because I couldn't take one more step. My son had to go out to the parking lot to hunt down a motorized store cart for me. I can't go anywhere by myself anymore because I'm afraid of becoming immobile wherever I am standing or walking. I've tried wearing my pressure stockings every day & that doesn't help the swelling. I've been so scared I called my urologist, who I just recently got a clean bill of health from, to see him again & do all the tests again to figure out why my feet are the way they are. I just want to hear him tell my again that my kidneys are no longer sick & they are healthy. I have also tested positive for systemic lupus, lucky me. The thing is, I KNOW why, I just don't want to admit or accept it. It's being cursed with the double inflammation of having a combination of PsA & RA. Last week my rheumatologist raised my methotrexate to the maximum dose. It takes time for the increase of meds to start working so I am playing the waiting game, but, am not holding out much hope for lots of improvement. I am afraid to start biologics because I suffer a multitude of chemical allergies. I can't take penicillin or other antibiotics or NSAIDS because of anaphylaxis.
I wish you well & hope your suffering leaves you quickly. In the meantime, take heart in the knowing that you are not the only one suffering in these ways.
