My hamster is terrified after an accident:(

[Lma]

Yesterday one of my hamsters (Black Bear Hamster I think?) escaped and descided to hide under a wardrobe (there is a small gap underneath it) . While me and my dad were preparing some treats to lure him out , my mom thought it was a good idea to poke it with a mop (she hates hamsters,mice etc) . I ran to stop her and when the hamster came out it had blood on it's eye :( . We gently wiped it off and put him in his cage . Now he's teriffied every time I try to get close to him , give him some carrot etc . He screams , hits the food I give him and stuff like that . What do I do to calm him down/make him trust me again ?

I would give him a few days to settle back down by himself. Talk to him, but don't try to interact physically with him just now. When you do start to interact physically, take it very slowly, at his speed rather than yours. Hamsters don't appear to have long memories, so he will forget this incident quite quickly. However, please do watch his eye; he may be in pain with it and need it checking over by a vet.

Agreed with the above. Leave him be and keep interactions to a minimum. Prolonged change of behaviour may indicate pain however, so a visit to the vet is probably the next best thing.
