It could be nothing, but you should take your hamster to see a veterinarian just in case.
My hamster has had a red bump on his foot before. There is a bump because a) another hamster bit it or b) he got his foot poked somewhere. This isn't a sickness, so you don't have to worry. It will heal by itself.
The bump could be a cancerous tumor. If the bumps get larger, develop black scabs, and your hamster starts to poop blood this theory may be more or less correct. I am truly sorry about your hamster.
Hi there im Bonnie i have a white syrian hamster myself and hes a boy but my sister on the oter had has a girl it may just be that shes getting nipples or anything to a canser bump my male hamster developed a red bump that turned a darker colour i loked it up and found out it was just a mole from beginging to grow old.

I have a hamster with red eyes as well I have not seen your hamster and i don't know how it reacts but it if it reacts as if it were blind then it may be.
