### input:
Im eighteen years old and have a family history of high cholestrol/health problems related to blood pressure. I sometimes get random spasms in my left thigh and arm that are in rhythm with my heart rate. The spasms feel as though my blood is pumping through those areas very intensely, and can very often see my pulse in these areas with ease (moves the skin so much). Should i be concerned?

Hello. Welcome to Chat Doctor, and thank you for your question. I carefully read your query. Your young age and your family history about health problems are not in correlation with each-other, as risk factors for cardiovascular problems. This positive family history about health problems may be reflected later in your life, but I am almost sure that this is not the case at the moment. Clearly, these episodes of simple muscle cramps or twitching have become very worrisome to you. I understand that. This sense of fear to "what is happening to me?" produces higher than normal, pounding heart beats. If you have experienced any startling for any reason during your life, you could have had this feeling as well. As for the muscular spasms or cramps, if you get them very often sometimes, I would suggest you to run a blood level of calcium. Also, in some occasions, there is an obstruction of blood flow in a certain limb, due to assuming different positions while sitting or lying down, that obstruct the blood flow to a certain area. There, the pulse becomes more pronounced and, because of this temporary obstruction, other phenomena like muscle twitching and sensing the pulse, may be perceived. My opinion is that there is nothing to worry about. A low calcium level would explain muscle cramps, if they are becoming more and more often as episodes. Simple calcium supplement would correct the calcium levels, and the cramps would be gone. I hope this helps. Take care. Kind regards,
