Lip little swollen after 3 months after juvedum

Hello, i got my lips done by a professional doctor 3 months ago and now i started feeling its getting dry, so i started applying lip balm last night and now i feel its abit swollen, it doesnt show but i feel its stretched abit and previously the fillers started to fade and now it looks a little bit fuller. Might that be an infection or anything? Should i be worried?
