Hi, For about a month or two, I ve been having headaches in the back of my head, and behind my ear. Along with these headaches, I ve also experienced weakness in the left arm. It feels heavier than the right, but I can still move it without a problem. When it first started, I felt imbalanced, lightheaded, and my vision was slightly distorted for a brief moment and I had heart papitations. After that, the arm weakness, dizziness and palpitations continued from there on out. Before this all had occured, my lower back was in pain for about two weeks. I went to the clinic and they told me that I had hypertension, and am on the brink of diabetes. I have been eating healthy lately, and drinking a lot of water everyday. No juice, or soda. The only thing that I lack is exercise. There are also times when I have headaches behind my eyes. I have chest pain, and heart palpitations mostly at this point. When I press down on the left side of my chest, it hurts. Could this be the inflammation of the breastbone and ribcage, or is this something heart related? The reason I ask is because I had been to the ER before for chest pain, and they said it was inflammation. Please, let me know as soon as possible if any of you have an idea of what it is. Thank you.
