Can Botox Move After 3 Months?

From what you are describing, Botox that was injected into your forehead over three months ago isn't likely the reason for your recent eyelid concerns, at this point. Discuss with your physician the onset of these specific signs and symptoms and ensure you don't have any other issues going on before you continue with the cosmetic Botox treatments.

BOTOX socks in very quickly after treatment.  Certainly there is no free BOTOX at 3 months.  Muscle recruitment can change as the botox wears off but that is not what you are describing.  I recommend that you consider seeing an oculoplastic surgeon for an assessment of your drooping eyelid.  The American Society for Ophthalmic Plastic and Reconstructive Surgery maintains a geographic directory on their website to help you find a highly qualified surgeon close to home.
