Hello, the truth is that many do not like injections but I think it is a better option than taking oral medications where the pills tend to stay in the throat and cause discomfort and a bad taste in the mouth, the injection is preferable because it only We must stay calm.

The intravenous injection goes directly into the bloodstream, providing a faster effect to the person who requires it, so the intravenous injection is the most effective in relieving pain, the intramuscular tends to calm the pain but does not have an effect as fast as the intravenous injection.
