Hello, and thank you for your question. It may be that Rocky has an injury of his front leg, such as a soft tissue injury (sprain), dislocation, or fracture. The armpit is also where some lymph nodes are located, and swelling of these lymph nodes may also cause pain, which is indicative of inflammation or infection. I would try to ensure strict rest for the next 24 hours (no running, jumping, or rough housing). If his pain persists after this time, or if he exhibits any lethargy or loss of appetite, I would recommend taking him to the vet for a full checkup. They can investigate for a possible leg injury, check for swollen lymph nodes, and check for infection. X-rays or blood tests may be recommended to further pinpoint the cause. I hope this helps, and that Rocky is feeling better soon.
