I've had a cough and sore throat for about 2 days now but all of a sudden the sore throat became so bad that I lost my voice, I'm having trouble swallowing, low fever (101.1), achy, chills, loss of appetite, runny nose, swollen tonsils, white spots of the tonsils, and grey-ish tongue (tried brushing my tongue for awhile and it doesn't change colors). I get strep often and I have antibiotics on hand but after I looked at my tonsils in the mirror with a flashlight it looks nothing like the strep I've had before. I just need to know if I need to go to urgent care (my insurance is only accepted at 1 in my town and theres always a 3-4 hour wait) or if I can use the antibiotics I have on hand, gargle warm water, etc. Thank you!
