I've been referred to a rheumatologist for suspected psoriatic arthritis. So far she's non committal but she's referred for an ultrasound which is taking weeks. In the meantime I'm in a lot of pain with my feet and ankles worn plantar fasciitis and Achilles tendinitis - some days it's so sore I want to cry. I know I need to lose weight but I'm so depressed and can't seem to find a way to exercise without having to bear weight on my feet - I can't even walk my dogs as much as I should. Swimming is not really an option for me. Any thoughts? Thanks.
