Medicine; Does it really work?

have you ever thought what a small tablet can do to our body?
when we are ill we go to a physician and get medicine..he or she will write some names of some tablets and capsules on a sheet of paper.happily we pay and get them and drink them.yea nowadays that's what most of us do.in this race we hardly have time for ourselves even when we are ill. so we just take some medicine and think it's over.but today after suffering a drug allergy i think i see this in a different way..
yea we get illnesses but inside us there is an immunization system in our body so when an illness comes we should let the system to fight with it and make its own reaction.but what do we do? we quickly take a pain killer or some other medicine.. so we don't get the use of immunization system which the nature has gifted us.and then sometimes the medicine we had react against us and we get allergies. then we have to take more medicine to cure it.
so i think its better if we don't get medicine as fast as we are ill we should wait a little and see.

yea this is an idea i got after suffering four days 'cause of a drug allergy,may be I'm wrong (actually i hardly know about medicine other the names of the medicine i have had I'm not good at medical terms so i beg your pardon if I'm wrong)so its up to you to correct me if I'm wrong .you are always welcome to comment on my posts.
