@Malak is he wearing tightish briefs? And maybe he should wear a pad / I know sounds silly but my DH wore the tight briefs and pad to help keep it all compact. With TESA did they take a large biopsy? Because he should have probably been better by now. Maybe there is an infection or a haematoma developing. Might need to get him checked up if he's not 100% - it's nothing serious but worth looking into.
