Hi I have been suffering with low blood pressure for a while and cope with it most of the time but I have felt dreadful over the last few weeks, feeling weak and light headed and a horrible ache in my calves. I have just bought my own blood pressure monitor and on average my readings are 89/57. This morning on waking it was 75/52. I usually have a headache every morning too. I am a 42 year old female, 5ft 7in and weigh about 10 stone. I went to the doctor a couple of years ago because I was having fainting episodes and I had my suspicions then about low blood pressure because I would occasionally check on my mums machine and also one in her doctors waiting room. My doctor said it was normal then. Any help would be much appreciated thank you.
