Painkillers- Good or Bad?

So I was reading an article on the NHS website on whether painkillers can be good for you or actually bad.
I'll post the link of the article below:

NHS article- Medication overuse headaches

It outlines the idea that millions of people use painkillers day in, day out to tame their headaches so they can continue work, but is it actually going to have the opposite effect. The effect is supposedly long term, so headaches worsen with the continued use of painkillers. The National Institute of Health and Clinical Excellence (NICE) believe that if you use painkillers 15 days out of the month, regularly then the patient should be reffered to a specialist. The constant overuse of painkillers is known as "medication overuse headaches"

The constant use of these NSAID's actually worsens the headaches both in terms of severity and frequency.
NICE also believe the only treatment to the condition is to stop using the medicine in question abruptly.

It is very interesting how what we may seem as something helping us and aiding day to day work, actually can prove to be very unfortunate in the long term.
