Hello RSD friend, I am new here and scanning thru. God bless you for all you have been thru at what seems to be an early age.
Yes, your suspisions are well founded. RSD was originally called Sudeks Atrophy whereas post Civil War the wounded soilders were not healing and showing great signs of Atrophy. Dr. Sudek was the first to document this problem.
I am 21 years with RSD. I had one great doctor who educated me greatly on signs and problem early on in this new life. He would mesure me from head to toe every six months. My head included seeming so silly as I had a leg and foot injury. I have a 2.3/4 inch difference in the right leg or orininal site.

I was fighting a 16 year workers comp issue and needed all the help I could get to prove the RSD. I was in the dark ages and the system did not recognize RSD as a ligitament problem.
A foot doctor measuring your head? That surely confused the court system and had to recess that hearing till all the lawyers did their homework on the Atrophy issue. IT IS REAl.

Not only of the bone but muscle, and everything else that is in there. I have been Systemic for a long time.
My hat size has even gone down since.
I am getting older but this is not just age.
God bless n keep you strong.
Peace & LUV, Andrea. RSD from MARS with L.U.V.
