I am 56 years old, about 5 3 and weigh 176. I have hypertension, high cholesterol, CAD, mild asthma which is brought on by irritants, Hashimoto s Thyroiditis, and Diverticulosis (I had a colon resection 4 1/2 years ago). I often get terrible muscle cramps in my lower legs, but I have also been experiencing this feeling of pulsating (it almost feels like something is crawling inside my lower legs) and you can actually see it puckering. I ve also had a few episodes of extreme dizziness, immediately followed by swooning (feeling like I was going to pass out), and simultaneous tingling & numbness in my lips, fingers & toes. These may be two completely different problems, but for all I know, they could be related. Any insight you could give me would be much appreciated!
