Hi doctor. I have a cystic tumor, many small cysts on both sides of my chest. Just now, suddenly, my heart beats fast, then my hands and feet are cold, my mouth is shaking, my teeth are twitching. After being like this, sometimes I feel cold in my body, a bit afraid of water because I am afraid that the water will make me colder, so I often take a hot shower, I take a shower at 9-10 a.m., after coming home from work. The doctor asked me if I had a stroke? What is the cause of the above situation? Please advise, thank you doctor.
