Four months ago I was at the gym performing lying leg curls when I felt a pop on the right side of my lower back. The next day I experienced extreme lowerback, buttock, and right leg pain. Had an appointment with my chiropractor, he performed some massage ultrasound therapy on my lower back, behind the knee and pelvis. I woke up the next day feeling close to 100%. Now, fast forward two weeks, returned to the gym and did some front squats. with no problem. Woke up the next morning with no pain present but severe dizziness and leg weakness. Especially bad at the supermarket and other stores, Walmart, Home Depot etc. MRI of brain came back normal. Bloodwork is perfect. I am experiencing no pain whatsoever just constant leg weakness, kind of feels like the floor is floating.. My legs are having a difficulty adjusting to changing floor surfaces, when I go from a carpet floor toa tile, I get really dizzy. Im fine when sitting. Its so frustrating! My first neurologist didnt have a clue. My second neurologist is going to send me for a lumbar spine MRI this week. Anyone experience this? Im not experiencing Vertigo, its a constant state of dizziness with weak legs.
