you need to come off everything and begin hcg and arimadex. I would use arimadex at 1/2mg 3 x wk and hcg at 250iu twice wk every wk and attempt to restore any natural test I could. The adex and hcg should help elevate sperm count and natural test over time. I would also use clomid at 100mg/ day for a couple wks and then drop to 50mg day for 2 more wks after you quit everything. Its going to take awhile, possibly a year before you are fertile again. Even on trt there is still a 50% chance of being fertile, but the choice to come off totally or stay on trt depends on how long you have been on trt up until now. If its been a year then Id attempt to drop everything, if its been longer then Id revert to a minimum trt dose of 80-100mg wk and continue on hcg arimadex regimen. U really need a fertility specialist though but for now this is what Id do personally
Swab the area very well and slowly penetrate the 18g pin directly into the abscess. Keep pushing the pin in and gentaly aspirating every few millimeters until you hit the cyst. Slowly aspirate the cyst. You should be able to draw out the initial volume injected and then some blood and puss. You can expect to drain out 3ml from a 2ml injection 4-5 days post injection. This will give your immune system and the anti-biotics the best chance of fighting the infection. Always complete the course of anti-biotics even if the symptoms and swelling subside.
