I received my second dose of Dysport in December and 3 weeks later got a terrible cough and wheeze. It's 3 1/2 months later and the symptoms persist. I've had chest x-rays, CAT scan and allergy scratch tests but everything has come back normal. A friend asked me if I had gotten Botox because she had the same symptoms for 4 months after her treatment. Could this be the case with me?
