Hi I am sorry you are in extra pain. Me and cold are horrid aka why I moved to FL. I wish I had more advice other then warm baths and micro fleece. I mean when I was in MI I had microfleece everything from sheets to pj's. I don't get a flu shot. The reason being pre rsd/pn I had the flu every month with a fever for I would say 3 years. It would clear up to come back with a fever a few weeks later. No clue why. Anyhow I got PN and RSD 2.5 years ago and since then have had the flu 1 time so I guess that is why a No for me. Everyone is different and I think there is no right or wrong and just depends on that person. Hang in there and feel better
