I have been editing my Kepler Bb story and after Robin gets a nasty stomach bug that causes projectile vomiting and thus abdominal muscle soreness he has this pain all over his body. The stomach bug lasts for 5 days and it is an unknown pathogen(Possibly a super version of salmonella since he was handling eggs) The pain is so great that he can't get up. Even breathing is painful. It seems that whatever he was infected with not only caused projectile vomiting but also sent a myotoxin all over via his bloodstream to cause this paralyzing pain. Now I looked up "pain paralysis" and all I got was "Pain does not cause paralysis. They are 2 separate phenomena that have no relationship whatsoever." But this super stomach bug Robin had seems to be enough to prove wrong that pain never causes paralysis. And I am sure that there are people who can't get up or have difficulty getting up because of pain. I once got a bruised tailbone. It lasted for several weeks. The first few were extremely painful. During that time, I slept every night on my stomach to avoid pain. And every time I was getting up or sitting down I did it slowly and often leaning forward so that I could minimize pain. The last few weeks were painful still but not cringing pain like before. Anyway, yeah I had trouble getting up and sitting down due to pain and pain alone. So is it possible to be almost completely paralyzed(practically only breathing and even then, shallow to minimize pain) due to an all over bodyache? And how would Robin tell Grandma that he is in extreme pain and needs pain relief now while minimizing his pain? Or would Grandma just know from the look of him that he is in a lot of pain? Here is the scene in question: Now here, Robin is 5 years old and I looked up morphine in children and it is fine to use for extreme pain. Morphine used to relieve extreme pain doesn't have all the addiction side effects that morphine used for any pain does. So would Grandma know Robin was in extreme pain just from the look of him as I have written in this scene or not? Would she really use morphine right off the bat for paralyzing pain instead of step by step pain relief(so maybe acetaminophen first then naproxen(extra strength ibuprofen) then morphine)? Would she know something is wrong if Robin is late for breakfast? Would she have to be very delicate in her injection when Robin is already paralyzed from pain? I mean I know you don't want to inject into an artery by mistake since that causes severe bleeding(gushing, likely to die(platelets just can't repair an arterial bleed fast enough to stop it)) but do you have to be very delicate to avoid an artery?
