random. So, you know comics with Johnny suck/injured??
Oh do I know comics where Johnny is injured. He gets sick less often but then he can boil his blood, so. If you want some sick!Johnny content, check out Ultimate Fantastic Four #13-18.
Also check out Matt Fraction's Fantastic Four and FF runs. His Fantastic Four run features Reed (and later Sue) hiding the fact that the Fantastic Four are being killed by their powers, which begin to fail them. Notable for the scene where Johnny, who can't stop burning, is impaled on a piece of metal and has to be stitched up using Sue's forcefields to keep him from bleeding out. FF features Old John Storm, a traumatized version of Johnny from an alternate universe. Both are good for Johnny whump.
Injured!Johnny, a reclist. This is not comprehensive; I keep almost asking if people want me to post the Johnny Fainting Collection again but I would have to post it in parts because I'm pretty sure the tumblr image limit is like 30 images and that won't even get us out of the Kirby/Lee run. You truly have no idea how much this boy faints.
Someone check on him please.
I'm going to go ahead and blanket rec Johnny's Strange Tales era, which is Strange Tales #101-134 and Strange Tales Annual #2. (This is Johnny and Peter's first official teamup.) Not every issue features Johnny getting injured, but a very common formula in it is "Johnny Storm, America's sweetheart, gets in some kind of trouble and needs help/manages to rescue himself/nobly tries to sacrifice himself." It's very fun. Johnny gets tied to the railroad tracks! Johnny gets tied to a street sign! Johnny... gets tied to a porpoise. I especially recommend Strange Tales #112: Johnny nearly dies absorbing the explosion of a dirty bomb. Very classic "everyone thinks The Character is a vapid showoff until The Character nobly sacrifices themselves to Save the Town and then everyone regrets their harsh opinions and cries about it."
Fantastic Four #25-26: Despite being seriously injured, Johnny joins the others in fighting the Hulk.
Fantastic Four #170: Johnny is injured in a fight.
Fantastic Four #191-193: This is more on the emotional hurt side of things, although Johnny is also injured at the beginning. When the Fantastic Four split up, Johnny's at a loss emotionally. Reunited with his best friend and college roommate Wyatt Wingfoot, their mutual friend racecar driver Rebecca Rainbow worries Johnny might hurt himself. (P.S. Bring back Rebecca Rainbow.)
Fantastic Four #244: Following his girlfriend Frankie Raye's decision to leave Earth and become Galactus' new herald, Johnny goes missing for days only to collapse on Frankie's roommate's sofa. Again, this is more emotional hurt, although he is in bad physical condition when Sue and Reed go to find him.
Fantastic Four #263-264: Johnny is kidnapped by a billionaire theme park owner who is Definitely Not Walt Disney At All and forced to go nova over and over for his plans.
Fantastic Four #296: Blaming Johnny for Ben's suffering, the Mole Man attempts to permanently disfigure him.
Fantastic Four #337-338: Possessed by a mysterious blue woman, Johnny experiences debilitating pain.
Fantastic Four 2099 #3: Johnny gets shot and has to cauterize his own wounds.
Fantastic Four v3 #35: Johnny is captured when Diablo invades Pier Four.
Fantastic Four v3 #63-64: An explosion temporarily deafens and blinds Johnny. Later, he's knocked unconscious when he and Ben are buried under the rubble of a building.
Fantastic Four v3 #69, Fantastic Four #501: These issues are very close together, renumbering is just lying to you. While trying to rescue Franklin, Johnny is badly burned by hellfire. The experience shakes him badly.
Fantastic Four #508-509: Ben is possessed by Doctor Doom, who attempts to kill Johnny, with tragic consequences.
Civil War #1-2, Fantastic Four #538: Johnny is badly beaten by a crowd of civilians and hospitalized following the Stanford Incident.
Fantastic Four #559-561: Johnny is kidnapped by his one time fling Psionics and a mysterious crew of figures from the future and used as a Galactus battery.
Dark Reign: Zodiac #1: I feel remiss in not mentioning this, especially since there's been conversation around it recently, but I don't actually recommend this comic. I think it's an unpleasant read, to say the least, but you asked for injured Johnny content, and it does fit the bill. Johnny is attacked and badly beaten by Zodiac, rendering him hospitalized. CW for homophobia and what is at the very least if not flat out implied then a metaphor for sexual assault.
The Negative Zone (Fantastic Four #587, #600): When people talk about the Negative Zone in relation to Johnny, they are talking about a very specific incident in Jonathan Hickman's run where Johnny purposefully seals himself in the Negative Zone to save Ben and the kids. Trapped for two years, Johnny is repeatedly killed and resurrected while being forced to fight in Annihilus' gladiator battles. While technically you can get the whole story from #587 and #588, I recommend reading Hickman's Fantastic Four run up #604 and his FF run from #1-16. (#17 is the Spideytorch roommates issue, which is a delight, but not exactly heavy on the hurt.) More on the emotional hurt side of things, although he does get thrown around a lot, I also recommend Annihilation Scourge: Fantastic Four.
Uncanny Avengers #18-20: Uncanny Avengers has a couple good examples of hurt!Johnny, but I'm going to single out the time he was possessed by the Red Skull, who threatened to kill him in front of Spider-Man.
Amazing Spider-Man #799-800: Johnny is attacked by the Red Goblin and injured.
Fantastic Four: First Family #6: This is the last issue of a retelling of the early days of the Fantastic Four that I don't generally love, although I think it raises a lot of interesting points, but in this issue Johnny is mentally transported by a psychic villain to his worst fear. Good stuff.
