I was trying to look up information about blood clots as I have pain, redness and a knot in my leg. It is impossible to navigate this site because it lists 1 thing on each page with a tiny bit of information and then you have to click to see the next page. The ads that continually pop up on top of what you are trying to read make it impossible to find out anythiing. If you are having symptoms of a stroke or something serious, PLEASE go to another source to get help. This one is ridiculous.
