I was running and twisted my foot sideways now i can't put pressure on while walking and my ankle is hurting a lot?

See a Specialist: You likely sprained your ankle, however there is a possibility of a fracture with any twisting of the ankle and continued pain. It's important to stop activity until healing occurs. I would recommend you getting an xray and further treatment for proper healing.

Yikes.......: You need to use the RICE treatment protocol. Rest, Ice application, Compression and Elevation. Re-evaluate tomorrow. If not better then use crutches until you can see a specialist. A walking cast boot may be necessary to help with the heal.
