I have epididymitis, going on for 7 months now. Please help.

28M. 7 months of epididymo-orchitis (right testicle) - started 2 weeks after I received my 2nd dose of COVID vaccine, at the end of June 2021 (which makes me think that's a side effect of it). Been to 2 different urologists and 3 ultrasounds. Ultrasounds showed everything looks normal, besides that I have epididymo-orchitis. Urologists did urine, semen and blood tests too - no bacteria, infections or tumour markers were found (been with the same partner for 10 years anyway). Hormone and testosterone levels are normal too. Sperm levels are extremely low, but this is likely caused by a surgery I had as a child (undescended testicles) and I've already accepted my infertility. It also never caused me any problems before the epididymitis started 7 months ago anyway. No antibiotics were prescribed as there is no infection. They just told me to take ibuprofen when it hurts, or if it continues, Ibuprofen eases the pain, but it usually comes back shortly after. Symptoms :pain comes when I sit or lay in bed for long period of times. When I am standing or walking the pain is non-existent. Epididymitis is thick , as well as the bottom of my right testicle (feels like the surface is harsh and I often get sharp 1-2 seconds of very bad pain there, accompanied with itching too - this has only started in the last 2 weeks). After ejaculation, the pain is briefly relieved, but then it starts again on the next day. Any suggestions? I don't know what to do. This is getting me really depressed and it's affecting my mental and physical state. I am fearing the worst - getting the right testicle removed. I am losing sleep over it and on the verge of a mental breakdown. Thank you.
