I seriously doubt you could damage a solder joint with the force of your hand. Unless you are superman.
Same. I actually was trying to remove an outside sillcock on a home, someone told me it was a "screw on" type. Having limited plumbing experience, I cranked the hell out of that thing with a huge pipe wrench, finally tearing the copper . The solder joint remained intact! But the force it took to do the damage is not something you could do with just your hand. I would guess you are fine and the real plumbers here concur.I'm sure you didn't damage it. I've cranked the hell out of one with a pipe wrench trying to attach a union without it leaking, and didn't damage the soldered copper line.
