Vitamin 'I' also called Ibuprofen

Harmlessly, the painkiller ibuprofen is called vitamin “I”. The danger of taking it the wrong way is thus downplayed. Too many thru-hikers use it while hiking to fight through the pain instead of listening to the body’s alarm signs and shifting down a gear. It is good to have ibuprofen or similar painkillers in your pack as a backup for emergencies. It can be useful to take this overnight to reduce any inflammation. Also in exceptional situations where pausing the hike is not an option. Ignoring the body’s alarm signals risks long-term physical damage such as a stress fracture. Ideally, if possible, contact a doctor and ask for advice.
