I sprained my ankle 4 days ago and it just started bruising however my middle 3 toes are still tingling and numb. is that normal?

Yes: Yes that is typical of an ankle sprain. Injuring the anterior talofibular ligament causes swelling into to the outside of your foot as gravity takes effect.The ecchymoses ( bruising) is also normal as the injured ligament does bleed a bit. Numbness in the toes is commonplace as the swelling is close to the digital nerves in your foot. This also will go away. Best of luck.

Have it evaluated: Numbness may be a sign of nerve damage or compression. Have it evaluated by a professional.
