A very serious cold is going around that has more of the symptoms for what you are describing. Many of my patients and staff have had this cold, as well as I have, and it lasted for a good 3 weeks. It doesn't have anything to do with Dysport and is mere coincidence that is came on after your treatment. It's just a winter cold.
