I would do a computer search for free clinics in your area. Or call the county health nurses. They would know of free or sliding scales health centers. In my area they have free clinics on certain days- first come first served.

Since your last labwork showed your kidney function was a little off, I worry that your kidneys are losing the ability to concentrate urine. Some of your meds may be metabolized by your kidneys and, if this is the case, your kidneys could be stressed by the medication.

I wouldn't mess around with this. Definitely try to find a free clinic or contact your public health nurses. Where do you live? I could try to do a computer search for you.
