Dear Welcome to HCM We understand your concerns I went through your details. I suggest you not to worry much. Such tell tale symptoms used to be found in the sufferers of anxiety disorders. Initially they are stressed. Stress gives them some muscular sprains and strain. These muscles pulsating whenever it over strained. Once the stressful period is over, the muscle takes a little time to come back to normal. For that person, he is already anxious about the pulsation, and he again and again doubts about the pulsation even after it gets cleared. Such a problem is called obsession. You are obsessed to the pulsation thought and that is the reason you are feeling it. Low concentration, restlessness, mood swings, irritation etc are part of the problem. The best method of treatment is ignorance. Just ignore the pulsation and the problem shall be solved within a fortnight. Take my word for it.
