My mom got out of rehab walking well with her walker. Two day later her legs feet swelled up again. Her prednisone was tapered from 20mg to 5mg in 2days then discharged to her apt. Presently her left leg Is super swollen even now her knees(right leg is swollen but 1/2 the size as left). Her right leg was good. Has less feeling in her left. Now she says her right leg feels like lead. Can barely walk-very unsteady Could tarring her prednisone cause her to crash? Really don t you make enough?
