You can't sue for damages.  Workers compensation is the only remedy you have.  But workers' compensation isn't just about medical treatment, and you may end up have some permanent partial disability, which you can get payments for.  You should find a good lawyer who does workers compensation cases, and have him or her handle your claim.

In addition to medical expenses, workers compensation will pay temporary total disability, usually at 2/3 of your regular pay, if you can't work while you're still in treatment.  Once your treatment stops, if you still can't work, you're entitled to permanent disability payments.
