Dumb move symptoms and conditions

Taking this for "cellulites of the face" which I guess basically is a bacterial cyst on my chin that has caused an infection to go into my lymph nodes, which are all very swollen (even ones that I didn't know I had!). After taking 3 doses, we went to a water park for 8 hours (dumb move), and even putting SPF 50 on every 1/2 hour, my skin literally felt like it was melting off of my arms. And it was just my arms, no other part of my body. The second sunlight hit my arms, I immediately got this burning, tingly feeling. The morning after I was expecting to see that my arms were really burned, but they look fine. Other than that, so far I am just extremely tired.
