I posted recently about a swelling in the supraclavicular area. I had an ultrasound and nothing found which is fantastic but I've just received the blood test results I also had and my platelets count is high. Just over the normal range. Also have low ferritin. GP surgery said re do blood test in a month then make an appointment. Bit concerned about the high platelet count as when I googled that, cancer was what came up. Does anyone ha e any experience of high platelet count?
