One wonders how much of these reports is politics and how much is science. Well, we can only take it at face value.
I do take Ibuprofen occasionally (fact is I weep that the expiration date on small containers has lapsed before I use them up) and always felt if I had to take it too regularly I should also be seeking other remedies such as physical therapy, orthodics or ace bandages, other medication ... medical advice.
My approach is to view it through the same thought process as an investment. Is the risk worth the return?
In the case of Ibuprofen I think the risk for most people is probably very very low and the return high in eliminating pain. However, that could vary drastically from person to person and an understanding of the pathology behind the pain could effect the decision of how much, if any, risk to take.
For example, if the pain is muscular, grit your teeth and bear it. The cause is not enough use of those particular muscles. Hike more.
If the pain is inflammation with no other damage, then ibuprofen helps.
If the pain is say from worn cartilege, ibuprofen may only mask something that needs to be addressed more seriously.
My analysis also considers that from time to time the ibuprofen upsets my stomach, a dminishment of the "return". Damn ... I hate the trade offs ... will it be ibuprofen or jalapenos ...
