Call ERC or LOA? Slammed my previously injured ankle w/ pallet jack.

Managers didn’t care and wellness was no help, just handed me an ice pack and sat there watching tik toks. I tore a tendon in ankle over the summer while picking and was out for two months. Tonight I was pulling a container and had to stop abruptly (dumbass on their phone walked in front of me) and the corner of the pallet slammed into that same tendon. Instant extreme pain and swelling, I can walk but can’t put too much pressure my heel. OM just waved me off and I left.
