My Ds is 13 and has been having a dull ache in his testicals for the last few days. He has only told me this evening (we are close but who wants to talk to their mother about their balls) and I have given him some painkillers and said we will visit male doctor tomorrow if they are still hurting. Have had a look on-line and some sites suggest that it could be hormonal (build up of sperm??) and just wondered if anyone knows if testicular pain during puberty is usual?
