Coral Scrape infection

I am researching an infection that started on my right index finger. I was cleaning my salt water aquarium (11/23) and scraped my finger on a rock. No big deal until it grew into an infection. The infection has spread to my what I believe are my lymph glands on my arm. I have pics if anyone can help. I live in Chicago and need assistance from someone fimiliar with salt water infections. Please pass my email to someone who may be able to help if you are unable. Thank you for your time: Steve [email protected]
