I'm Janne NIssinen a board certified neurologist. You are describing cauda equina syndrome which is a compression of the lower nerve rooms of the spinal cord. Have you had any spinal imaging?

No my insurance denied doctors request for MRI. Should I go to the hospital er?
Expert:  Janne Nissinen replied 8 months ago.

You should definitely be worked up. The cause is often some sort of compression of the nerves. I can't say what exactly but it needs to be worked up, it can result in paralysis if neglected. How long have you had the symptoms? Are they getting worse? Any injuries to the back? Any history of cancer?

Onset was approximately 2 weeks ago with initial symptoms being altered sensation in groin area, I thought I had a UTI. Lower back increased as well. I have had 13 reconstructive procedures on my knees so I have suffered from chronic pain for years. The numbness and "" pins and needles " sensation in groin and back of legs has gotten worse everyday. I Cant feel my feet at all.

Thank you very much doctor for your help-i truly appreciate the information you provided and also making me aware to head to ER. I have had lot of medical problems through out my life but whatever this is going on is scaring me. What should I expect regarding treatment at er?
Expert:  Janne Nissinen replied 8 months ago.

It depends on what the cause is, but if there is found to be compression due to structural cause then surgery is likely. But take it one step at a time and find out what is going on first. I hope all goes well.
