There's most likely no point in suing: in a lawsuit, you can only recover an amount of money equivalent to your out-of-pocket medical bills, lost wages due to the injury, if any, and--IF you suffered *serious*, long-lasting impairment or disability--an amount for pain and suffering...but to possibly recover pain and suffering, you'd need to hire a doctor to testify, and you can't get the cost of hiring the doctor back in the lawsuit (it's your cost). So in a case like this, you could only get the medical costs and wages for any work you missed, and *possibly*, if you suffer a signficant lasting effect from a 2nd-degree burn on your arm (which is unlikely) a few hundred dollars or so for pain and suffering--but would have to pay several hundred dollars or more for the medical testimony. In other words, you will spend more on this lawsuit than you will get back.You could file a police report and inquire into pressing charges.
