I got diagnosed yesterday.
My doctor diagnosed me with Juvenile Arthritis. After multiple blood tests, X-Rays, doctor visits, and an MRI, he discovered that I actually have multiple cysts in my hands and wrists which may need to be surgically removed. He doesn't know how I had gotten arthritis; it could be genetics. There is also the possibility that I acquired arthritis from when I was seriously ill, and instead of fighting the disease, my body fought against itself and did so much damage that it caused me to get arthritis.
The plan he has for me is to go to physical therapy, take some medications, and visit a hand surgeon to see if I need surgery.
And I am most likely never gonna march again.
