Feeling desperate would like some advice
I am female. Within the past 7 months I have had 3 kidney infections. They have all started from untreated utis. The first kidney infection happend after an ex used baby oil instead of lube without telling me. I was completely fine before that and never had a uti. Immediately after this incident I developed a severe uti and a kidney infection that put me in a lot of pain. I was treated for it and went back normal. I continued to have sex with said ex, each time developing at least a uti, and a second kidney infection at one point. The second infection was partly my fault as I waited too long to go to the hospital. I was put on antibiotics again. I broke up with the ex and am seeing someone new. I thought that my ex was the one giving me the infections. But after being intimate with my new partner I developed another uti. I went to the pharmacy and had it treated with standard uti medication, but it still spiraled into a kidney infection. I took a different course of antibiotics from the one I took for the first two kidney infections. I still have pain and discomfort in my kidney dispite finishing the course of antibiotics, although it’s lessened. The doctor prescribed me nitrofurantoin 100mg to take each time after sex. A couple days ago me and my partner were intimate, without any penetration, and despite taking the antibiotic I started to feel symptoms of a uti. I countinued to take the nitrofurantoin twice a day for three days just in case. I started to feeling better so I stopped. And the symptoms came back. So now I’m taking it again twice a day but I’m not sure if that’s the right thing to do. I’m really upset because this could’ve completely been avoided if my ex had just used lube. I’m scared to have sex now and I’m worried for my health, I am already immunocompromised and I’ve spent a significant amount of time this year on antibiotics which is suppressing my immune system further. I’ll add some further information for context. My UTIS are rarely ever painful but I experience fatigue, odd smelling urine, and cramping, and when it becomes a kidney infection my kidney cramps and hurts and it spreads into my back. I have been tested for STDS with negative results. Despite experiencing kidney pain and cramping above my pelvis my urine test results after treatment are always negative. I am now taking d mannose, cranberry supplements, probiotics, as well as NAC. Sex is my only trigger.I eat very healthy. I’m wondering what am I doing wrong, has anyone experienced UTIS similar to mine and how did you deal with it?
