What are the symptoms of artery blockage or necrosis following filler injections?

Thank you for your question.  Injection of fillers can disrupt the blood pattern of a particular artery or vein through either compression or an accidental injection into either blood vessel.  This is a particularly rare complication and can be associated with pain, skin discoloration with either a bluish tint to the skin or pale white skin, swelling, and skin breakdown.  Please see your physician to ensure that these complications are not occurring. 

Symptoms include pain, change in color, swelling, skin breakdown or pus pimples.  I suggest if you are concerned to see your physician.  This is a rare complication but can occur from direct injection into a vessel or from compression of the filler around a vessel.  Best, Dr. Emer.

Pain is always a symptom that something is wrong, however, it might not be serious.I'm continually amazed that patients take the time to ask this kind of question here rather than call their doctor immediately, which is what you should do if you haven't already done.Pain, discoloration, or swelling are three of the symptoms that can occur with vascular occlusion which, fortunately, is rare.

If you are concerned that you have skin necrosis, you should see your physician immediately.Skin necrosis is a very rare side effect of Voluma, and would only occur if the filler was causing compression of a blood vessel in the area it was injected. Signs of skin necrosis include changes in skin  color (a blue, dusky, or dark hue in that area), pain, and “breakdown” of the skin. It’s worth noting that after any surgical procedure, cigarette smoking significantly increases the risk of necrosis.As I tell everyone, the most important decision you make after deciding to undergo a cosmetic procedure is choosing your Dermatologist. An experienced physician who performs these procedures on a daily basis will provide the best results with the fewest side effects.

Just having pain after an injection in you nose is not likely impending necrosis.  Pale skin, followed by bluish tint in areas well beyond the area injected is needed too.  It then will turn dark, sometimes black as the skin is dying.  A superficial infection can occur too.
