I walk about 2 miles a day, not all at once though because it hurts too much. I also get up and move around at my desk. Is an unbearable itch a symptom? I have a spot on my back, very localized, that itches no matter what we do. I have my hubby scratch it, use a back scratcher, scrub it and even put lotion on it. There is nothing visible other than the scratch marks LOL.
