So sorry to hear about your recent struggles. I was recently diagnosed with Stage 3a CKD. Kidney problems are serious mainly because there is no way to reverse the damage done to kidneys. You can influence the future and the rate of decline, but there is no way to reverse it. Please ask your PCP for referral to a nephrologist ASAP. Then let the nephrologist take the lead on the drugs you are allowed to take. Immediately eliminate all NSAID (non-steroidal anti-inflammatory drugs). Tylenol is it for OTC pain help. Tell your doctor to report you as allergic to Aspirin/NSAID, tell your pharmacy also. My nephrologist did some research for me around an antibiotic I needed. They can help you decide on the best drug for the purpose.

Diet is also a very important part kidney health. If possible give up refined sugar - it will also help with your PMR because sugars simply feed inflammation in your system. Control you salt intake and monitor your blood pressure since elevated blood pressure is a common cause for kidney damage. I will be seeing a CKD diet specialist soon to help me understand what I need to do diet-wise to control potassium, protein, sugar, salt and other nutritional considerations. Kidney problems can be managed and you do have control. I am finding it takes a lot of self-discipline. My nephrologist has me see her twice a year plus seeing her nurse practitioner twice a year, plus seeing their diet specialist twice a year. Half of the visits are telehealth. Tests run every 90 days, so I cannot go too far off the tracks without being caught. They also watch my thyroid levels as well.
