Have you ever had jigger/chigger bites? That could be what it is. They are tiny red things that bite you, burrow under the skin and lay eggs. It sounds super disgusting, but they're really pretty common depending on where you live. You can buy chiggarid or something like that at the pharmacy and apply it, or just apply clear nail polish to the affected area all the time to kill them. You may want to go to the doctor anyway as it may be something else entirely.

I'm experiencing the same itchy and irritating bites underneath my skin also. First experienced it about 3 months ago. Initially thought I had been bitten by a spider on the inside of my right forearm. The nodules were the same size and shape. The swelling was similiar to that of a mosquitoe bite but the only difference was they were side by side. No sign of punction wound on the site of swelling either. I put applied rubbing alcohol on and around the apparent bite wound and the swelling went away in amount 15 minutes. I thought maybe a jumping spider was living on the center console of my arm rest inside my car. Oddly enough about 3 weeks later the bites reappeared! I would experience a strong allergic reaction of itching and watery eyes. It has since occured a gain for the third time in three months!

Does anyone have any idea if this could be a parasite or localized allergic reaction to something I'm coming in contact with?

I don't know it is definitely scabbies or not, but that's the first idea that I had from reading both posts. Chiggers could be causing the problem on you ankles, but I was of the impression that they only attack during the summer when you've been walking in grassy areas.

Here's a link to the scabbies symptoms and treatment:

if it's only between your legs, it could be a heat rash or a similar rash. I'd CALL your doctor and ask.( it's free that way). If he can't give you an answer than you might want to go for a visit.

I share the same symptoms as chillstreet, everything from the appearance to the skin reaction. Please respond back if you can identify the cause of this.
