I completed my last dose of metronidazole 4 days ago and also took fluconazole after completion. I noticed a yellow tint on both sides of my tongue the Friday I completed the last pill and took the fluconazole. I was instructed to take metronidazole 2times daily for 7 days. During the time taking it i experienced pain in muscles, jaw pain, headaches, dizziness, sweating, pebble like stool... and now even though I have completed the antibiotics I have been experiencing some of the same symptoms along with hives/welts here and there on my arms, legs, forehead really all over my body. I am having a heartburn like feeling when i swallow and my ears also itch inside when i swallow... I am also waking up to sweaty thighs and sweat stains on my sheets. My fingers and hands hurt and look swollen... I took an hiv test 2 weeks ago after having unprotected sex April 21... here it is May 22 and I’m not sure if my problems are due to the medication or to the fact that i may have hiv/AIDS which is my biggest fear. Please help.
