Anyone experienced side effects from ACTH/LHRH testing?

Has anybody on here suffered a worsening symptoms following an ACTH or LHRH test?

I’ve been making steady improvements in most symptoms of late. Skin was becoming very greasy, genitals were not normal but much more comfortable than in the weeks following my crash, semen seemed to be a bit thicker etc.

However, I had both tests yesterday morning and at around mid morning today genital shrinkage returned. Anybody know if this is common in a) the general population or b) amongst PFS sufferers?

Very worrying.
