I was bitten two days ago by a fire ant, three times on my middle toe on my left foot. It became inflamed and red very quickly. I used benadryl, it stopped the itching. Yesterday morning the swelling had spread to all 4 small toes and into my foot. My doctor prescribed prednisone and topical steroid cream. Also told me to take zyrtec or clariton over the counter. I took the steroid and it seemed to reduce the swelling but by the evening two of the insect bites were black and the surrounding area was also black and swollen. I soaked my foot in epsome salts that helped the pain and reduced the redness and swelling some. Today the bites are still very black and swollen but not exceptionally painful. Should I be concerned? Should I lance them and soak again?
