Good news, the doctor found out why my arm is hurting!
He was working once a week with my arm and after the visit I was feeling better but then the pain started to get worst just before the next visit.
I was starting to get worry but then he asked me to show him how I work on my computer and painting and there he found the problem. It is my posture! Without changing the desk I started to work with my left arm and it started to hurt too, so that was the problem.
I can start blogging and painting again without pain! my husband modified my desk and I bought a big easel. yay!
I leave you now with my "Russian Farmer Girl" a little 4x6 painting, right now available in a local store " The Homestretch" (I miss selling on line so soon I will be listing on Etsy or ebay again)
