Just take more, eventually your pain will go away, of course so will your respiratory drive
People are different. Not every patient reads the textbook, which why it is usually practicing medicine. I had a guy with no pulse, anywhere, taken by 4 different responders, who got up and walked to the stretcher. I put down "Rule Out Demonic Possession" for my impression on my paperwork. Got into a little bit of trouble for it. But, it is the example I give of why we must treat the patient, everything is not black and white in medicine.
