For the past few weeks I've felt these symptoms:

1. feeling weak in my legs, my workouts now feel a lot harder and my legs feel like they'll give out
2. tight legs and muscle cramps or spasms
3. random shooting pains around my body

My health anxiety started a year ago with this worried and has come back around. I've had a few doctors do basic neurological testing but no scans or bloodwork. What are the chances?
