My female boxer just started lymping.?

We noticed it Monday night. It appears to be her front left leg. She’s almost 2, never had any health problems. She is inside most of the time, and in the backyard the rest. We also have a male boxer that is 8 months old. They play rough sometimes, could this of caused a sprain or pulled muscle? They are both fixed. We gave her some dog aspirin last night. She doesn’t appear to be in constant pain. She does put weight on it when walking, sitting or getting up. I hate to take her to a vet only for them to tell me that it will heal itself, while walking out of there with a $200+ vet bill. If it is something that needs medical attention, then obviously I won’t let her suffer. What is your opinion?

It could be an injury from playing, although limping on a front leg can often be a sign of Lyme disease. There is no way for anyone here to say if it merits a vet visit or not. But since it hasn’t resolved & it’s now 2 days later, it might be something more serious than a sprain.
