Oh To Be Able To Take A Long Walk Again

I have had Psoriasis since age 7. I am now 55. Have never completely cleared. Went for light treatment when I was young, methotrexate, etc. About 5 years ago rather suddenly I was unable to climb the stairs without sitting down half way up. Fatigue was dreadful, felt like I was encased in cement. Then the joint pain came. It took 3 rheumatologists to finally be diagnosed after three years with PsA. I think I probably had it even in my mid 20's when I was having difficulty with heel spurs and also had one bout with uveitis. No doctor put it together with the Psoriasis. I've been on sulfasalazine for 2 years, methotrexate injections for 6 months and off that, and just started Humira 4 weeks ago. My skin is clearing, not much relief yet with joints and tendons. I also have Fibromyalgia, Sjogrens and Hashimotos, all diagnosed within last 3 years. Interesting how the autoimmune diseases seem to travel in packs. I certainly am not looking to run a marathon but would love to be able to just take a long brisk walk again and do some gardening.
