Rashes started from the groin area with a big ringworm like look but no itching and gradually spreading towards the thighs, very few at the back, chest and arms. After seeing it for the first time at the thigh area i immediately assumed it to be ringworm and took antibiotics to curb them.. But the med had no effect, though it faded a bit, after the medication and it started to spread towards my hands and back. Is this an allergy or a side effect from azithromycin i had few weeks earlier? This also started a couple of weeks back. I am also taking vb 7 right now.
