hey i'm sorry to hear this
but like what other people have said it may be the fluffy wool bedding I have heard numerous horror stories about the fibres sticking to the hamsters warm if you want to keep your hamster warm please use towel or shavings I use toilet tissue and kitchen roll I hand my hamster a square of it and then they will create their own nests.
thanks for reading please let me know how he gets on
