hi I am 50 years old,female and for the last hour or so I have been getting a little pain and numbness in my right arm,first it started in my forearm which is where most of the pain is and then it travelled up my shoulder a bit,but it is now mostly in the forearm area again,i also have like a numbness in my fingers,the questionnaire said I have high blood pressure which I do I am on meds for it,but I wanted to make sure it is not the sign of a heart attack,my friend said that is usually the left side for heart problems,are they right?
