Bad Dysport Reaction: Very Painful to Swallow, Impaired Speech, Head Pain. How Long Does Last? No Help from Doc.

Thank you for your question. Sometimes people can have flu-like symptoms with Botox or Dysport. I would report it to your injector so they can assist you and follow up on you. Injecting Botox/Dysport around the mouth relaxes the muscle, and so when speaking may not be able to pronounce certain letters/words. A very small amount gets injected into this area, so its very unlikely you can be experiencing botulism symptoms. I would also seek an evaluation with your primary care physician to be sure you are not experiencing stroke like symptoms. Be certain to be under the supervision of a board certified dermatologist or plastic surgeon with expertise in injectables for the safest and most effective treatments. I hope this helps.

Even when Dysport injections are performed properly, there is a chance that side effects may take place.  Two weeks following the injections is not an abnormal time for any side effects to occur.  Side effects from Dysport injections can include the following:

1) Bruising
2) Headaches
3) Eyelid ptosis
4) An expressionless appearance - (if too much is injected, or the injections are not performed properly)
5) Minor swelling

Duration and onset of side effects can vary from patient to patient, but generally will subside over a few weeks to months.  It is likely that your flu-like symptoms are coincidental with the treatment. I would recommend seeking a second opinion, and getting treatment immediately for the symptoms you are experiencing. I hope this helps, and best of luck!

Dysport has been reported to cause loss of strength or general muscle weakness, blurred vision, or drooping eyelids within hours to weeks of the treatment. It sounds like you are having serious side effects as a result of your Dysport injection. If the doctor who performed the treatment is not being helpful, I would suggest seeing an ear, nose, and throat doctor who can help you determine whether the issues you are having are a result of a reaction to Dysport or if you are having unrelated ENT problems. Best of luck.
