If side effects occur after a Dysport treatment, they are often mild and only last for a short while. During the session itself, there may be some stinging or burning sensations, and there can be mild pain or sensitivity to the skin around the treated area following the procedure. Some patients have experienced low levels of itchiness, seen some redness/flushing, and had rashes. Minor bruising and discomfort are treatable with ice packs or over the counter pain medication.
