I was diagnosed with ME in March and, after reading the forums here, took the advice of wearing a HR monitor. I have been trying to pace myself by keeping within my estimated anaerobic threshold. Usually my resting heart rate is in the 80s or 90s (although it does jump around quite a lot). However, this morning I had my first bout of the chills since wearing the heart rate monitor - goosebumps, feeling cold, feelings like someone walking over my grave and cold hands and feet. And my resting heart rate was low - in the 60s and often dipping into the 50s quite often. I was just wondering if anyone else had experience of these symptoms coinciding and if they know of how they are linked?
