How long for Infraorbital nerve damage to heal following 0.5ml of HA filler in cheek 10 months ago?

Dear Silverlining10,Thank you for your question. It is extremely uncommon, but possible, to have infraorbital nerve pain after filler injection to the cheeks. This injury is usually sustained by direct injury to the nerve or hematoma formation (which may not be seen at the surface). This complication can be avoided with basic anatomical knowledge of where the nerve comes out of the bone. It can take 12-18 months to fully recover, although I usually give this timeline for surgical questions, not injectable. You could try reversing the filler to see if that helps. If it continues to get better that is a good sign. If it is persistent, you may want to see a neurologist and try neuropathic pain medications if it is disabling.Good luck,Nirmal R. Nathan, M.D.

not sure if this is still an ongoing issue for you but why not get the filler dissolved completely? unless that was already tried? even if it was tried maybe there is still some filler left in there that's causing the pressure on the nerve. u never know. there are measures to resolve this pain. no reason for you to be in so much discomfort. 

I really havent heard about a case like  yours i recommend a second opinion and also improvement should come when the HA dissolves after 1 year
