Diagnosed with this condition in 2015 after I fell and fractured my shoulder routine blood test then discovered high platelets and also had to have bone marrow test. Had no problems with condition or treatment until now as I am now beginning to feel fatigue etc. Yesterday I was going to check out the theory about exercise giving you more energy by going to the gym but I sat down for a few minutes and fell asleep. You have to laugh but I will try again.
