Hi givinghope, it is constantly changing. Mine seems to be decreasing but at such a slow rate. The weird sensations on/in my back like hairs are standing on end and that's just one. I found that sleeping on the couch for 2 nights helped a smidge with the brain. We put the new air purifier in our bedroom last night and when I laid in bed, my left eye immediately burned and hurt. my sinuses were better. I'm a left side sleeper. I've been sleeping with 2 heating pads under my spine which helps with my spine pain BUT I'm starting to believe that my latex topper, mattress and pillow is causing at least my eye condition which started at the same time as the peripheral neuropathy. Either hypersensitivity to everything or HIGH VOCs. I'm determined to find an answer and get better and with this chat site, I feel finally someone understands so thank you.
