I also went down the Reddit rabbit hole of TC stories, I could almost say 100% that my symptoms were the same as the non lump guys. I had my swollen and achey feeling for about 4 months initially and tried EVERYTHING. Painkillers, leg and hip massages, ice packs, and a roller ball over the pelvis which actually released some tension, nothing else really worked.
It wasn't until I done regular stretches that the issue subsided.
This was my go to video for pelvic floor exercises:

Try it 2x a day for a couple weeks and see how it goes.
