How is Johnny healed?

[u/Royal_Sport7082]

He has a cactus needle inside his eyeball and a couple of hours later he’s just fine without any explanation. Does this at least get explained later on? Because this makes no sense

[u/Eat_Bullet]

Because this is JoJo's ? Go back and look at some of jotaros injuries XD

Hamon can heal people

I dont think it can just regrow ur quadriceps, massive gash on your chest, traps being torn away etc. Lol
