Hi Lara
Welcome to NeuroTalk

.
I am sorry to read about your back pain and headaches.
It might be an idea if you described your experiences in the Spinal Disorders forum (
https://www.neurotalk.org/forum22/) and also in the TBI/PCS forum (
https://www.neurotalk.org/forum92/).
Other member might be able to offer you support and good ideas.
All the best.
