I am wondering if it is possible for migration of filler to "migrate" and put pressure on an artery causing skin necrosis? Has this ever happened?
Can Migration of Filler Cause Skin Necrosis?

Skin necrosis with dermal filler
Yes it does and yes it can.
My response to your question/post does not represent formal medical advice or constitute a doctor patient relationship. You need to consult with i.e. personally see a board certified plastic surgeon in order to receive a formal evaluation and develop a doctor patient relationship.
Filler and necrosis
Usually when skin necrosis occurs it is from direct injectioninto the vascular system. It is unlikely that migration of the filler causes the skin to necrose.
