My hands arealways cold & now my knuckles are blue, what does this mean? do i have to go to the hospital? almost always cold

Always : Always to most people mean that is something that has been going on for a long time. If that is the case then you may not need to rush to the hospital if always means that all of a sudden it happened and now its there all the time then you should call your pcp or see someone. There are many reason for cold hands and purple knuckles. The purplish cast of the knuckels sugggest a disturbance in circulation. What causes the circulation disturbance well thats what you want to find out. The list ranges from chronic circualtin issues due to smoking, atheroscleosis, or hardening of the arteries, hormonal or endocrine problems including diabetes, or thyroid didease. Arthritis, inflammatory disorders, neurological problems, medication, or just beng someone who tend to have cold hand and feet. The key thing is to have your general health checked out to rule out other issues but if it is new and sudden then gat to see a medical provider soon.

I'm : I'm going to answer assuming that this is a bother rather than an emergency. It's usually easy to tell the difference. There is a range of response to cold. We all protect our core temperature (our brain, heart, lungs, etc.) by reducing the circulation to our hands. Some of us do this better than others. At the far end of the spectrum, people reduce there circulation so well that it is referred to as raynaud's phenomenon. A doctor can check to be sure there is no underlying problem, but most people with this issue are healthy. In fact, as a person who gets cold, mottled hands in the cold, i can tell you that the line between normal and disease can often be difficult to draw here.
