I've been dealing with lower back pain and foot numbness/pain for 9 months. My back pain has improved but, my feet are getting worse. I've been diagnosed with peripheral neuropathy and my neurologist is running a bunch of lab work to determine what the cause is. Recently the PN spread from up legs and into the tip of my fingers. Today my lower face and jaw is tingly. Anyone else have neuropathy spread to their face? This is scary.
