Depending on your profession, you could be the type of person who uses a ladder day in and day out. For example, painters are always working on ladders. Just the same, roofers and construction workers use, sometimes extremely long (!), ladders to reach the tops of buildings.
If you suffer an injury on the job, there is nothing more important than obtaining immediate medical treatment. The last thing you want to do is assume that you can treat the injury on your own, as this can lead to more harm than good (in many ways).
