Currently undergoing blood tests and an ultrasound after thinking I had a uti. I masturbated (dildo) and it felt painful, then I experienced vulva pain, weak flow of urine and pressure in my abdomen, I was prescribed nitrofurantoin. Symptoms went away but then came back after I masturbated again (the dildo was clean and I stopped when pain started this time). Symptoms seemed to come back and I felt kidney pain. I then started ciprofloxacin but there was still kidney pain that developed in to upper back pain and pressure. I don't really have any urine issues it is more my back that's the problem, but I worry touching myself in any way makes things worse. For the time being I have stopped inserting anything but even quite gentle masturbation or thoroughly washing the area (just with water) seems to be more painful than normal, it causes almost a bruising feeling and I am scared I won't be able to enjoy sex normally again. I am also confused (if I did have a uti) at how easily it started. I have considered that maybe friction and pain make me more susepcibtle to an infection but even now being gentle is no better. Equally I have had rough sex so many times before and never got one.
