Eating foods with grease on them
You can have poor circulation, from sitting idle, and not moving around enough, or cholesterol in the arteries, blood clots, all kinds of reasons really, you should go and see a doctor if you are feeling that you aren't circulating well enough. Hope this helps, good luck to you.
I have a possible blood circulation problem in my left arm. I am saying "possible", because I haven't been diagnosed yet. I have this problem more than a month. I don't know what's the reason. I have seen a doctor, he didn't really figure it out. The problem is that my arm is so sensitive to weather changes, and I always feel a pressure, like someone compresses my arm. Usually it gets completely paralyzed. I can't carry anything heavy with my arm. Recently I have been to a doctor again, and this time he asked my for blood analysis.
High blood pressure, not enough exercise
Narrowing of the arteries.
