Sure, every now and then, we've all taken a pill for a headache or a bloated stomach without having the doctor's recommendation or prescription. And this isn't a problem if it happens rarely and it doesn't form a pattern. But once the same ache repeats itself and becomes chronic, you could deal with a serious health problem, and you should make an appointment with your family doctor or a specialist. The only thing self medication can do is relief pain, help decrease our body temperature when we have a fever, fight dizziness and PMS symptoms. But if this mild disease happens often, it's time to see a doctor. 

Analgesic medications or pain relievers fight only the symptoms and not the cause, and when administrated on a long term they could lead to secondary effects, such as gastric disorders. They will also dely your decision to meet with a doctor and receive a correct diagnosis. So, self medication is only a short-term solution. If you want to really be well, make an appointment with a doctor!
