Wondering about if I have endometriosis. Looking for answers.

Hi all.

I wanted to reach out for some guidance. I am a 24 year old female. About a year and a half ago after I got my IUD taken out, i began having extreme urinary urgency and frequency. I was going about every 15-20 minutes. I also had low back pain that began at this time, and low grade fevers. I talked to my GP and I was tried on a bunch of different antibiotics even though I had negative urines. Finally she tried doxycycline and tetracycline for suspected pelvic inflammatory disease. Long story short I had severe esophagitis and ended up in the hospital after multiple ER visits. I was admitted for 5 days but I finally got referrals after this. I also had a lumbar spine MRI which was normal. Urology got me in for an urgent cystoscopy which only showed inflammation in my bladder and a mass pushing in on the posterior wall of the bladder which they didn’t seem worried about. I also got a SI MRI which was normal. Since then I was on a bladder med, solinifican, but had to go off it because my constipation was so bad. My doctor and gyne think it’s endo. Now I am on progesterone and am still struggling with low grade fever, night sweats, and still some frequency and low back pain. I asked my gynecologist for a specific ultrasound referral for endo but she didn’t want to but wants me to try Lipron. I feel like I’m so young. I just want to get back to my active self and get my life back. Any suggestions/ideas? I appreciate any ideas.

Thank you so much in advance.
