As a survivor of heart attack and double by-pass surgery myself, I m writing in behalf of a dear friend who has just been diagnosed with Congestive heart failure, and ended up in the hospital a second time when the Elliquis prescribed for blood thinner cause internal bleeding. One of the symptoms that continues to plague her is clamminess and chills. She has this and whole body jitters and shakiness more evenings than not. We ve told her doctors, but don t get much of an answer. Is this something that s symptomatic of the condition, something needing more attention, or more of an annoyance just to put up with? Obviously, CHF is a pretty scary diagnosis, and as we learn more, these questions will get sorted out, but right now, she needs to know whether she should seek further medical help for?
