Physical Hallucinations. False sensory input from malfunctioning nerves. It really is weird. Symptoms come and go, but lately they stay a bit. The worst for me is the morning. Sometimes when I wake up the sensations freak me out. Then I get up and it all goes away. Some days are worse, Wet, hot, cold, burning, tingling all mixed up. Definitely weird. They say it’s from my back. MRI shows severe lumbar arthritis. Collapsing discs. So lose weight, physical therapy and drugs….
