Although, there is a scenario that the claim for the application of the drug could be rejected in case of a lack of a medical necessity, that is if it does not fulfil the usual accepted professional medical standards of care.

In this case, we believe that overheating or lack of exercise is something we can control. We believe we can feel the process taking place and we can react in time. We fear all the situations that we cannot control.
