get yourself some jockstraps. briefs are better than boxers because they give more support. Something like this is good.
No change. It is a regular testicle. Are you sure that you got it from UTI? Did urine samples show any infection? I saw a lot here that urine reflux to the epididymis can cause this. I think you have to evaluate your condition both urologically and orthopedically. Try to remember activities you did before each bad flare ups. For me, it is definitely sitting too much. I observed it two times.
I also find some useful image for whom has non bacterial epididymitis and thinks it might be related to some nerve issues.
Pinched sacral nerve can cause groin pain. Scroll down to see areas it affects.
I have always had some numb thigh pain occasionally. But after epididymitis, it got more intense. Maybe something worsened whatever issue I had.
And also I recommend you and everyone taking painkillers and antibiotics. Be careful as you can get stomach issues Gerd or gastritis. Having stomach and testicle pain is terrible. Never drink alcohol while taking painkillers. (I recommend to wait to eat stomach unfriendly foods and drinks for a month after taking painkillers)
Take warm Epsom salt baths a few times a week. Also take Black Seed Oil (Nigella Sativa - the pure 100% cold pressed with Thymoquinone) on a daily basis. its a powerful anti-inflammatory, anti-bacterial and antiviral agent capable of suppressing chronic inflammation and many other issues. Its not snake oil. This is the best thing currently I take it myself. You can read and see videos about its many benefits all over the web including government and medical articles. You should see a difference after a few weeks or less.

It kind of fixed everything honestly. I was in the same exact place you are at. The antibiotics made the swelling and pain go away, but I could still feel the sensation of having it. After 3-4 days of using the silver I definitely felt a huge difference. I’ve only had one flair up since I first got it (around 1-1/2 years ago) and when I used the silver it went away within 2-3 days. Definitely try the smaller bottle to make sure it is going to work for you. Take it in the morning and at night. This was the bottle I got. Try the small one to make sure it works for you.
