I had a very small quantity of juvederm + restylane placed.That night I had a throbbing headache and extreme insomnia (which I never have) tossing and turning and have slept only approximately half hour.There's a huge pressure behind the forehead area and there's no way to fall asleep.In addition I would stop breathing when I was trying to sleep.i don't know if it's due to the bacteria proteins in these fillers as I do also have mites protein allergy.Has anyone else experienced this and will the insomnia eventually go away?I don't fault the injector.He was highly knowledgable,hygienic,professional,trustworthy etc and had great technique and I experienced no bruising or swelling and no infection or lumps etc.I don't want anyone to be scared off either as these reactions are probably rare and I'm disappointed that fillers don't agree either me as they produce great-sometimes life changing-results.
