I have lupus and fibromyalgia. When I started I had a rough time cause i couldn't last but only a few hours of work. My body grew stronger and I learn to ignore the pain to a certain degree. Of course I crash when I get home..But then I feel so proud of what I have accomplished.
Mind over matter..
My sister had lupus for 18 years , and this year. POOF.. gone !!!! she had the butterfly lupus coudnt be in sun, etc, I am sure you are familiar, her arthritis everything gone !! The doc told her sometimes it just happens, after so long it will get worse or go into complete remissson. (you just cant get a doc to say the word MIRACLE !)
To OP.. I have lymphadema stage 1 in one leg and stage 2 in the other, from shattering my knee cap into 7 pieces years ago. I have a stool that I use when working on cakes in kitchen like making icing, baking etc. , and I do all my detail work at my dining room table, where I sit with my legs proped up on another chair. Take frequent breaks and exercise the muscles to keep from cramping and seizing up. Oh and bow to the MOBIC gods. If you have never tired mobic, I sugguest you talk to doc about getting some. it really helps.
