Rather suddenly my left arm began tingling...kind of like pins and needles. It lasted over two hours so I took myself to the hospital. They did an ECG and ruled out the possibility of a stroke or heart condition and have referred me to a neurologist. My appointment isn t for another week, but since then I ve been getting random patches of goosebumps on my arm and sometimes left thigh and calf that come with an intense tingling sensation but only last about 5-10 seconds. Should I be concerned?
