If this stops the pain, your best outcome after trying everything else might be removing that right testes. You do need to fix your quality of life and stop been a science experiment. Please note that testicular cancer can be painful and removal is required.
If you did testosterone replacement therapy [without hCG or a SERM] LH/FSH would -->zero and the testes would probably shrink and that might do something, however, fertility may suffer. Some on T get a low level ache in their testes from low LH/FSH.
