i developed a hard lump durring my first and only cycle

quickly treated with nolva and gyno went away

5 months post cycle, the lump has returned

i have no previous gyno before the cycle

i have letro at my disposal, but my questions is, should i allow my estro levels to naturally stabilize, or use the letro and risk another estro rebound?

alcohol may be the reason my levels are wack, so hard not to drink in college though

will the lump ever go away without a pct? please advise
