5. Discoloration
If you are experiencing any kind of discoloration of a limb, then this could also be a sign that you are at a danger of developing a blood clot – or that you already have. Make an appointment with your doctor and find out what they think: Book a scan if this is considered necessary by your doctor, and get a second or third opinion if the problem continues.
The discoloration could make your leg or arm appear blotchy, or it can even go pale, blue or slightly red – and there are several things that can cause this, all of which mean that you should be seeing your doctor to find and root out the cause. Blood clots, like already mentioned here, is just one of the things that could be behind it.
Again, you could also be looking at problems with your circulation or blood pressure if you are experiencing any kind of discoloration. There are also other syndromes, such as Raynaud’s, which can cause this discoloration.
