Has anyone been bitten by a fire ant?

As the title says, I've been bitten a total of three times. My job requires me to water flower beds, and yes, there are still old buildings around these days, so I have to manually haul hoses to water them. The first time I was bitten, I thought it was just a regular small ant because I stepped on their nest. My feet got a lot of blisters, but I figured some medicine would fix it. I didn't see a doctor, just applied over-the-counter medicine, wore my sneakers as usual, and dragged it out for a month. The blisters wouldn't go away, so I finally went to a dermatologist. The doctor took one look and sternly asked, "Why did you come so late?! It was almost developing into cellulitis!" I was shocked. Honestly, I thought it was just a common Taiwanese red ant bite, and I didn't understand why it was so serious. The doctor said the toxicity clearly indicated a fire ant bite, and I shouldn't have waited so long. Luckily, I'm not allergic to ant venom, or I wouldn't have made it this far. The anti-inflammatory drugs were covered by health insurance, but the ointment and breathable bandages were out-of-pocket, and the follow-up visits before I fully recovered really cost a lot of money and time. The foot in the photo is in the process of healing (including the first and second bites), as I deleted the more gruesome photos. The hand is from the third time; I was bitten in the morning and it was swollen like that by evening. Some ask if this counts as a work-related injury. It does, but I didn't apply for it. When I calculated it (including the cost of the diagnosis certificate), if I really applied with the company, I would have to pay an extra 50 NTD. I only applied for medical insurance the first time; I didn't apply for subsequent ones for fear of the insurance becoming void. The insurance only covers the out-of-pocket health insurance fees, not the cost of the diagnosis certificate or self-paid items, let alone the significant waiting time for dermatology appointments. In short, I'm really not that lucky; I get bitten but don't win the lottery!
