i'm new and having Psoriasis on hands and feet I have been on a Prednisone roller coaster for 5 years. Sometimes being off for as long as 5 months and then having such an awful flare I'd dig up what i had at home and use it. Virtually every dr has cautioned me about staying away from it. My doses had to be increased each time to stop the flare and the flare last year was the worst! My lower legs/feet swelled so much and were bright red - Couldn't fit in a shoe and my pants were so tight! Trouble was it was in January and I could only fit my feet in slippers. During all this time I was trying different biologics that you see on tv - Humira, Stelara, Cosentyx, Taltz and also Otezla which is a pill. Dr. are thinking now that my results with these drugs were skewed by the Prednisone i took.
Right now I am back to only using steroid cream when hands and feet are bad. Feet are worse than hands but I am able to walk and go to work. I use compression stockings on my legs and that helps with swelling too. Dr. is thinking of again trying Methotrexate.
Bottom line is that if 5mg of Prednisone would have helped I would take it but as if was the last time i took it 40mg was not helping me. It kills me to know that if I took a high dose right now my whole body would feel better, no aches or pains, no swollen legs or psoriatic feet and would not have to wear gloves at work as my hands would heal up like magic. I equate it with quitting smoking which i did 3 years ago. I thought smoking calmed my nerves and was okay as long as i only smoked a little. It was hard to quit but I did it for the greater good of my health. Now I am trying to keep off Prednisone. That is a little harder. Good luck to you and I know how good it is to feel better. Many blessings!
