I had a fall onto concrete on Tuesday(Australia) and have a grazed and bruised temple which has now become a red bruise right round the eye and blue down the cheek. I also have what feels like bruised ribs. I went to the emergency department at the hospital they examined me and cleared me of concussion and no treatment other than a tetanus injection was given. I am due to fly to Canada (15 Hours) on Saturday morning. Is it safe to do this. I am 72 years old.
