It's best to wait to hike after a sprained ankle until you're pain-free and your ankle ligament feels stable. This can take anywhere from a few days to several weeks, depending on the severity of the sprain. Listen to your body – if there's still pain or weakness, it's not healed enough for the demands of hiking, climbing, running, or other outdoor sports. Gradually return to weight-bearing activities like walking first. If pain persists or worsens, consult a physical therapist to ensure proper healing and prevent future injuries. A proper physical therapy plan can help reduce swelling, restore strength, and improve mobility in the ankle joint until you're able to bear weight again. Remember, a sprained ankle can sometimes lead to Achilles tendon issues, so prioritize complete recovery before tackling challenging hikes like you would any sports injury.
