streptococcal infection
"Had a secondary staph infection from an athlete's foot problem.  Went to ER, gave me some antibiotics (forgot the name).  Five days passed and no relief; saw a dermatologist and he put me on the Levaquin.  First night was like World War III in my foot.  Almost ran back to the ER, but you could feel this medicine working.  Two days on the pill and swelling and redness subsided significantly.  Third day, I could walk again and zero pain from the infection.  This medicine works. Now, I'll admit that I've had sore Achilles tendons and I could feel the medicine working its way up into my knees.  However, considering the pain I was in, I am okay with the trade off. Very expensive medicine - but works!"
