I was helping my mom with her lawn on saturday and when i was done my ankle was very swollen, it's been 4 days and it's still swollen. it doesn't hurt?

Tissue Reaction.: With only one ankle swollen, there is a distinct possibility that the swelling could be due to an unrealized insect bite. Another possibility is that overusing the ankle, especially on uneven turf, has strained the soft tissue elements of the ankle. The response would be swelling to stabilize the strained tissues. To remove all doubt, consult with a Healthtap specialist of your family doctor.
