Hi. My 2 year old Syrian hamster, Oreo has a lump under her mouth/side of her front left leg and her back right leg seems to be weaker but she is still walking fine and hobbling a little now and then. This has just occurred today (16.10.2019) and I'm slightly worried. I think its nothing but I'm really not sure and I'm slightly worried.

Thanks for reaching out about Oreo Cookie. A lump under the mouth or on the front leg is something to be concerns about, whether an abscess or tumor, and should be assess. A lump on the face needs to be differentiated from an impacted cheek pouch (which could still be a problem). Wobbliness of the back leg could be a trauma, spinal arthritis, or other problem, and likewise should be investigated. So, a veterinary visit is recommended to provide a plan for diagnostics and treatments. Monitor appetite and water intake. Good luck.
