A few days ago I became incredibly cold and used coats and blankets and heating pad to warm up and this was on a 30 degree summer day I fell asleep with this an woke up a ought an hour later feeling much better I did not have damp clothes or anything that would suggest a fever. Later that day I could not walk right and I fell and my muscles would not work right. I had other symptoms of delirium including visual hallucinations. I have peripheral neuropathy for the last ten years I take lyrics and tramodol
