My wife picked up some hypoallergenic laundry detergent with no scents added. The sheets are comfortable and neutral. I have something else going on in my calf muscles. A deep itch that is extra painful when subjected to hot water in the shower. My calves look a little like the effect of congestive heart failure, but I doubt that is the issue. I suspect I was exposed to the original SARS in March 2003. Both legs were swollen.The ER did lots of tests. No diagnosis. No treatment. Just a big bill. I had to walk on my treadmill 20 minutes per day for 3 months before I could put my shoes on again.
Keep trying options. I also found that alcohol and chocolate will disturb my sleep. Lots of restless hours before finally settling down to sleep.
