39 but looking back I think I had symptoms as early as 28 and it slowly progressed.
I was 39 when I was officially diagnosed but I was unofficially diagnosed at 38 I was going through chemo when I was officially diagnosed and constantly in excessive severe pain often collapsing as my legs failed to hold me up under the pressure of the pain
At 19 or 20, but for years prior I suffered from constant pain throughout my body. I'm almost 22 now
Just diagnosed this year, I am 43.
