Polymorphous Light Eruption: HELP??!?

Two weeks ago, unbearably itchy rashes formed from my knees down and from my elbow down. After being misdiagnosed with staph infection, follucellitis, and hives, I visited a skin doctor who said I definitely had polymorphous light eruption, an allergic reaction to sunlight. I am by no means an "outdoors" person so I found this weird at first. Since then I have avoided sunlight and have been using a topical creme (which has greatly reducted the itch). However, a rash is beginning to form on the bottom of my face. Could this rash be a possible allergic reaction to all of the strong medications that I was initially prescribed for staph (which I don't even have?) This is becoming more miserable by the second. Anyone who's dealt with PMLE or rashes, it would be great to hear your opinion. I appreciate it.
