Hi,Dear thanks for the query to HCM.
I went through details of your query and understood the health concerns you had.
Its a complex issue for you, as your husband is operated for right hernia,followed by intermittent pain in left testicle.
In my opinion after detailed study
a-last of week fever
is a cause of worry and indicates URT which needs to be ruled out with prostatitis
b-Your husband need to do FBS and PPS to rule out the diabetes
as the cause of the post-operative infection and the cause of UTI now faced by him.
c-This pain does not appear to related to earlier hernia repair
but re-check is essential to rule it out.
d-You should not wait but I would advise you to consult ER Surgeon who had done that surgery earlier and get his opinion on the facts discussed above.
e-Advise is that you should be worried and treat it ASAP on the lines given above.
Wellcome for any further query in this regard.
Wish you fast recovery.
Have A Good Day.
