Hi there, my husband was bitten on fri 18th april by an inch ant, in Birdwood S.A. The bite is on his right, inner bicep. It has slowly developed into a very itchy, sore to touch, deep red lump aprox 2 inches in diameter. It is continuing to spread around the bicep to aprox 6 inches in diameter not as red in color but can be seen clearly. The area is tight, swollen and hot to touch. He used savlon to start with then has tried Cortic- DS 1% ointment a couple of times. We are wondering what to try next. I have some Phenergan 25mg tablets which he hasn t tried yet. I am concerned it may spread into the glands under his arm pit. Is that a possibility? Thanks for taking the time. Regards Kris
