I had the problem of intermittent heart rate increase. the HR increasing to 150 plus on occasions. I consulted Cardiologists at a local famous branded Hospital who advised me to undergo Doppler’s Test. Prior to the Doppler’s test, a preliminary test was done by the doctors at the hospital. But after that test, I developed a strange complication. I have intermittent pricking pain at the shin or thigh region of my right leg. At the ankle region and above it, there is a marked skin discolouration with a collection of dark venous blood which has not cleared even after many months of the test. Will someone through this website guide me suitably to help me out of this situation?
