I dont have headaches, i have something crawling sensation in my left head comes and goes and my heart beat goes up, what it could be doctor? please tell me?

Without an exam it cannot be diagnosed. Your heartbeat goes up for you worry when you get that feeling. Pl. see your MD soon . Good luck

Your physician will check for any scalp problems. My sense is that you're experiencing a nonserious issue like an irritable superficial scalp nerve and that this will resolve over time. It's a relative of neuralgia. Your heart rate will increase from worry and anxiety, as has been mentioned. Stress management therapy is very helpful for chronic stress and anxiety.
