Since Sunday I keep getting an odd pulsing sensation on the inside of my left arm just above my elbow. I seem to get a similar sensation in my chest too at the same time. I also keep experiencing a sensation in my left arm similar too when you get your blood pressure checked and again I seem to have similar sensation in my chest.
There may be issue with your heart also. I suggest taking ECG and treadmill test and as per the report take suggestion from cardiologist if there is any issue. Now if every thing is normal with heart then check with your blood pressure and take needed steps if it remains high on a regular basis. You can also Learn stretch exercises from physio for your upper limb muscles and nerves. And practice it regularly if there is no other issues. But any time if there is a breathlessness on exertion and if you feel there is a pain in chest along with this then immediately go to hospital for proper treatment and management. Also do regular walking and maintain good diet. Do not eat heavy in night and do not sleep immediately after dinner. Have different color fruits also in your diet. I am sure if you follow this properly then it will be useful for you. Take care.
