Balanitis? Nerve Issue?

Hello!

I'm a 42 y/o male that has been dealing with chronic pelvic pain for over a year.

My primary symptoms are:

- Pain near the tip and underneath my glans
- Redness around the tip
- Painful ejaculation
- Sensitivity all around my glans with movement

In addition:

- I've had arthritis like symptoms since 2019 of unknown origin. Back, hips, and feet primarily.
- I get buttocks pain if I sit for too long and occasional pain down my right calf.
- I was on clarithromycin for 4 months prior to this all starting, which may or may not be related.
- I had an MRI done in 2019 that showed a disc impingement at L5-S1 with narrowing on the right side of my nerve roots.

I've seen four urologists - did a cystoscopy, whoch showed mild urethral inflammation, tried 3 rounds of antibiotics, nothing helped. They sent me to pelvic floor therapy, which I did for 4 months. I did have a tense PF, but after awhile the PT said she didn't think PF was causing my pain based on my progress.
- 5 dermatologists, who have speculated on psoriasis, eczema, and fungal infection. No creams/ointments have worked. I even did a glans biopsy (ouch) but it didn't tell us much.

My next step is neurology, in case this is nervous system related.

Multiple urine and semen tests have come back clean, aside from occasionally having trace blood in my urine.

Any thoughts on how I can figure out if this is a skin, nerve, or muscle issue? Or something else?

Thanks!
