Cheek fillers 7 hours ago. Is pea size lumps normal? (photos)

Swelling and lumps can be typical. Icing, firm massage and cold compresses may give improvement. I would wait a full 2 weeks before judging the results. If it is after the two week wait, you can have the filler reversed with hyaluronidase.
I hope this helps!

Dear Jolie, 
I am sorry to hear this has worried you. This can be a normal reaction after having dermal fillers and will normally settle within two weeks. Cold compress can help with swelling. If the lumps do not settle then request a face to face review with the practitioner that injected you. 
Hopefully all will settle and you will love your results at two weeks. If you are still unhappy at two weeks then HA filler can be dissolved with an enzyme. 
Good luck

Thank you for your question.  Based on the photos provided this looks to be just normal swelling.  It is not uncommon to see lumps while your body is still healing from the injection.  
Swelling and bruising can take up to 2 weeks to subside. At that point I would recommend following up with your board certified physician or experienced injector if any lumps are still evident.
