Best of luck! It really depends on how quickly your tests are read, if the results are definitive, and how quickly your provider gets back with you. So, I imagine your wait time will be as individualized as you are a person. It all depends on your paradigm, at that time. For myself, I was turned away for 23 years, by doctors, ignoring my symptoms. By the time I finally got MRIs, I had hundreds of lesions in my brain, 🧠, and down my spine. I did not require the spinal tap. So, your time for a diagnosis may be variable, to say the least.

All the best. As I'm in the UK I can't help with how long the results will take. I would say that you want them to take their time & give you a correct diagnosis - it's not always easy to tell. Good luck
