There were no external causes like bites or stings. The swelling in his leg is blood that is pooling from an unknown source. Based on bruising, somewhere between his elbow and armpit area. Our fantastic vet suspects a muscle tear but was perplexed because she couldn't actually find it by touch. We are treating symptoms and preventing infection and hoping for the best. If he's not improving in a few days the next step is an X-ray to rule out an osteo related bone crack (apparently this blood pooling presentation is consistent with that, but his pain reactions to extensive manipulation were not). Thanks to all for your replies!

Not yet, vet has us giving vetprofen until she examines him. Fingers crossed for simple solutions like this! Ouch! So this guy has bad luck he spends the least time outside of all three dogs (2 greyhounds and 1 doodle)

I can't see anything but he's very reactive about it. Given that we will be at the vet tonight I've decided not to mess with him too much and upset both of us in the process. Last summer he did have something, maybe a stinger, in the top of his foot that led to a similar (but worse) infection with swelling so thank you for putting that back on my radar.

Our 11 year old male started limping yesterday. We noticed a soft jiggly mass on the back of his front left "elbow." Over a few hours the leg started swelling. It's now swollen from elbow to wrist along with the soft mass at the elbow, limping persists. We are quite sure it's not a hygroma after consulting with our vet remotely, as those should not be painful. There was no known trauma and I haven't heard any screaming in the last few days so the cause of this is really unknown. I'm driving him out to the vet this evening but am wondering if anyone has any ideas as I sit here and worry... Thank you for any input!
