You didn't state your symptoms, which could help us give input, and I'm hoping your Dr. is a good one, but if baby is showing no signs, and the med isn't working, I'd have the Dr. check you for mastitis, which requires an antibiotic. Washing the toys and all that won't do much. Mastitis is a toughie, but easily cured if you catch it early, can get quite serious if you let it go.
As far as insurance, you, of course, are not alone. If something like that happens again, contact your doctor's office and tell them. If you get resistance from them helping you, call another time and ask to speak with only him or his nurse - they'll probably have to call you back. Many doctors will lower or forgo a fee for a temporary problem if you are a good customer. But don't just take no for an answer without checking w/the office manager or doctor. It's the doctor's business. Do know that mastitis is serious enough not to wait on and Urgent Care is an OK route to go. Urgent Cares are also able to help if you are financially challenged, too, if they aren't one of the private, for profit ones (like StatClinix). As far as meds, many doctors will give you samples if they have them or ensure they give you a low cost generic when possible, and then you can use Target's or Walmart's $4 program. Just be frank about your situation. In my experience, doctors would rather have you healthy than have you very, very ill. I've actually seen a couple of doctors charge me just the copay I would have paid under insurance when there's been an insurance issue. It's worth a try..all they could say is no. And if so, I'd look into finding a doctor who cares. Of course, your goal is to make this temporary so they have a good, HEALTHY, paying customer with insurance soon.
Google mastitis (WebMD and Wikipedia) are good starts. Feel free to write back or send me a message if you need more info on mastitis, as I'm a repeat offender in that field (to the point of needing hospitalization - it caused sepsis in my case.
Good luck, and don't let it wait...as you see above, I've learned how serious it can be if not caught. Kiss baby and let us know how it turns out.
