How do I fix my anterior tibialis

I hurt it running long distances in shoes that weren’t meant for running. I was on a run outside over a month ago and it started hurting really badly. The pain is concentrated on a spot in the middle of my shin.

I feel like I’m going crazy bc no matter how much I ice it or rest it or wear compression socks it still hurts. Walking or standing for a prolonged period is rly frustrating. My big toe on that foot constantly feels like a finger that needs to be cracked. I stopped running and have only been cycling but I have no idea what to do and I really need help.

Please help
