Bad Headache from Botox Injections, When Will It Stop?

I had Botox 1 week ago and have had a horrible horrible headache for a week. My forehead feels heavy and my right eye is achy and heavy. Nothing helps! I thought Botox was supposed to eliminate headaches but this has caused a tremendous one that is relentless. Will I have to suffer for 4 months until this wears off? Dear God, that would be awful. Please help:(

Bad Headache from Botox Injections, When Will It Stop

Some people report a 'botox headache' that happens soon after the injection of Botox for cosmetic reasons and continues for about 4 - 7 days. I suspect it is due to the weakening of some of the muscles which is a temporary thing. It is unlikely to last for the entire duration of 3 months. Over the counter analgesia should help.

Botox On irritable and bad headaches

Depending on how your body reacts to Botox, side effects may be experienced. One such side effect, though a rare one, is headache. However, these are often resolved in just 24 hours or less.

Based on what you have described, it could be possible that your headache might be caused by straining. Your forehead has a muscle and this muscle helps keep the eyes open through straining. So, you may actually be using your forehead (muscle) frequently to make your eyes stay open hence the strain.

When you undergo Botox injection, Botox weakens this forehead muscle. Therefore, if you strain for your eyes to be open, the strain will give you mild to intense headache.

If straining is indeed the reason, the headaches could persist until the Botox wears off or until your forehead muscle regains its strength, but not 4 months though. Sadly, it can go for as long as a number of weeks. Should you undergo Botox again, inform your injector of this case and ask for a milder dose.

Post toxin

I have not seen this, but can imagine that it is rather bothersome. 

I would see your surgeon first thing and maybe they have some input. Often times asymmetries can lead to an uncomfortable feeling so maybe correcting that will help.

Best of luck,

Bad headaches

Headaches are a rare side effect of Botox, but they usually resolve within 24 hours.  

Given your description, I wonder if you are used to using your forehead to help keep your eyes open.  Botox weakened your forehead muscle so now you are straining to keep your eyes open.  This strain is giving you a headache.  

If this is the reason, then your headaches will probably last until the Botox weakens and some of your forehead strength returns.  This does not usually take four months, but it can take several weeks, unfortunately.  If you decide to have Botox again, I would recommend a lighter dose.

Bad Headache from Botox Injections

Botox can create headaches for a short period. The most typical reason is that the Botox may have not been mixed in a conventional manner. Consult with your treating physician as he or she knows the scope of the treatment and the specifics about you.

Botox Headaches

Some patients do experience headaches after Botox while others don't experience one at all. When Botox headaches do occur they are normally mild, do not last more than a few days and are easily treated with ibuprofen. Botox is FDA approved to treat migraines, so a headache from the injection should not typically last that long or be that severe. If it does, I recommend seeing the physician who did the Botox for further evaluation. “Dr. D”

Headache with Botox

While Botox is approved to treat migraine headaches, it can also be associated with a mild or dull headache that can occur after injection into the forehead for cosmetic use.  I generally warn my patients that this can occur and tell them that if a headache does occur, it should be mild, easily treatable with acetominophen or ibuprofen, and should not last more than a few days.  If you experience a headache that you have never experienced before having Botox, I would recommend being seen by the provider that injected the Botox for an evaluation.  A "heavy" sensation, which I consider to be different than a headache, may be due to too much Botox being injected into the upper forehead.  In most cases, this sensation will ease with time, but prior to the 3-4 months it takes for the Botox to wear off.

Botox and headaches

Yes, Botox works to help alleviate headaches, but with that being said, sometimes people get headaches from the injections themselves too as it's basically a slight trauma to the area. These headaches usually stop within a few days, so I'd think yours should subside any time now. If not, please see your injector as something else could be going on. It should NOT last for four months at all!

Headache after Botox, Dysport, Xeomin

Headache is one of the most common side effects after a Neuromodulator injection. Although it is not common to get any side effect from the injections, when it does happen it usually last a few days to few weeks. If it severe and continues you may want to be seen by a doctor for further evaluation.
