Is it normal to have a headache 2 weeks straight after Botox on forehead only?

While headaches may occur after Botox, they generally don't last weeks after treatment. If it persists, I recommend following up with your Doctor. Botox results resolve in 3-4 months. Best, Dr. Emer

Thank you for sharing your excellent question.  It is common for some patients to develop a headache after initial Botox injections but this may occur in the first 24 hours after treatment.  By two weeks your botox should have settled in, helping avoid headaches.  I would discuss your symptoms with your injector to make sure all is well.

It is possible to have headaches post Botox injection. Most of the time it occurs when the needle is injected deep. Inversely it helps some people who do have headaches.

Thank you for your question alvt88. I understand your concern. Botox is a purified protein used to address wrinkles associated with facial expression. When injected into the skin Botox will relax the muscles and smoothen out the overlying wrinkles. The most common areas of treatment are in the upper face. These include the horizontal lines seen on the upper forehead when one raises the brows, the vertical lines seen between the brows when one frowns (frown lines), and the crow's feet seen around the eyes when one smiles.

A headache from Botox is possible but a persistent headache lasting two weeks from Botox would be highly unusual.  I would consult a neurologist to evaluate your headaches.  Please keep us posted.  Best, Dr. Green
