I am in a clinical trial for IPL for MGD. I have had one treatment with the next 15 days after. I am into day 7 and two days ago I started to get a blocked nasal passage. My right hand side is completely blocked like I have a bad cold. My left hand side is normal. The trial was on one side only, they don t tell you which side has had the placebo effect but I know it was my left hand side as my right eye has felt more comfortable since the treatment plus I felt a ping off my skin on the right side but the left nothing. Can the IPL have caused this terrible nasal blockage, I feel like I have a head cold on one side of my face?
