When i press the epididymis i catch something like a ball i imagine it is either the tail of the epididymis or the head of the epididymis but when i catch it it hurts a lot is it normal for it to hurt? ?

Kali mera, Kirie. Yes, it is appropriate for pressure to cause pain in the testicle, but the "ball" may be a hydrocoele, so see your physician for an exam, as epididymitis can also cause pain and should be treated.

Sometimes an epidydimal cyst can do that. Get an Ultra sound and see a Urologist. This is a benign thing and usually the pain goes away. Wear a good supportive under wear and try not touching the area. You should be fine
