question: Overnight I noticed red itchy blotches like bites appear on the wrist and spreading towards the top of my right hand ...not in the palms. Its red in color, looks likes bites - but am sure it is not! and yes,it itches. Recently I had applied Thrombophob ointment on the same hand, prescribed by the doctor as I had long IV drips from the same hand. Could it be the result of the same? Doctors, please HELP! Thank you a zillion!
