Since the cause of your injuries in the workplace exposure to chemicals you need to talk with a local worker’s comp. attorney ASAP.

I'm not a NY attorney, however you can not sue your employer for a work related injury. Sometimes you can sue a third party, for instance a customer of your employer or a supplier of equipment or chemicals. You do need to consult with a NY workers compensation attorney, preferably one who also handles personal injury and products liability.
If you still work for this company you should report your injury to your employer immediately and seek medical care through their workers compensation carrier. In my state the statute of limitations for worker's compensation is 1 year, but if you are suffering a flair up you may be able to protect your rights by reporting the injury now.
I am adding Workers Compensation to the Practice Areas of this question.
Dear Madam or Sir in Patchogue:
Sorry about the answers from out of state attorneys.
You cannot sue your employer.
However, although you evidently did not file a Workers' Compensation claim, as you should have, you may still be able to evade the Statute of Limitations.
Your time to file a claim runs from the date a doctor FIRST tells you that your leg infections, etc. were caused by exposure to workplace chemicals, etc. So, see a doctor who accepts workers' compensation matters and ask him to fill out a C-4 form that states your 1) history of exposure at work, 2) his diagnosis, 3) that the diagnosis is CAUSALLY RELATED to that exposure and 4) whether you were unable to work for a period of time, causally related to the exposure or 5) if there is a permanent loss of function in the foot or leg and in what is the Schedule Loss in percentages.
You do not get compensated for a disfigurement on the foot or leg, but only for loss of function.
If there is no permanent loss of function, yiou would at least get your medical bills paid.
The foregoing is based on the little information provided; additional facts may change the comments given.
Caustic soda (a/k/a lye) is not an acid. It is a chemical base (highly caustic metallic base and alkali salt).
