I've been keeping a diary and can see a pattern. Once every two or three weeks I wake up feeling a bit poorly, slight sore throat, as if I'm coming down with a cold. The worst symptom is feeling cold. Really cold, can't get warm, sometimes have to go back to bed wrapped in a duvet or have a hot shower. No temperature. Anyway, that passes, but the next day I feel achey, exhausted, joint pain, almost hungover. This lasts for about 48 hours then I feel fine. It's almost like a migraine, but absolutely no headache!
Any bright ideas? I'm 56, on hrt, take lots of vitamins, normally active and healthy.
