Assalam ulaikum @abdul-rakib
Thanks for your nice message. Medicine has helped a lot in healthcare but it is also helping many people get better. Giving medicine through a needle can be really important for some illnesses that makes the treatment work faster. Your point about being careful with how medicine is given is important and showing how much doctors and nurses matter in keeping us healthy.

Your kind words mean a lot and I'm thankful for them. Lets celebrate the good medicine does and the caring people who give it. Wishing you lots of health and happiness.
