Weird Lumps on my WTF's back

[Kmoonleaf]

Hello, about a week ago, my frog started acting lethargic, and i noticed his back legs were weak, with the toes curling slightly. I assumed it was either an impaction or early-stage MBD, since i had not been dusting his crickets with vitamins in the time i have owned him (6 months). He pooped yesterday, which rules out impaction. He's getting repashy calcium plus on his crickets now, which should hopefully heal any problems he may have had due to lack of vitamins.
Over the past two days he's perked up considerably, no longer acting lethargic, climbing around his tank and croaking just like normal. I'd say he's all better, except that he has these lumps on his side, and his right leg still seems weaker than normal. I've looked everywhere and haven't been able to find a case similar to mine. The lumps aren't hard, don't seem to be an abcess or bacterial infection. They feel just like the rest of his skin, and seem to be internal. Is this enough of an emergency to warrant taking him to a vet? He's perfectly healthy other than this.
