Hi my husband had a vasectomy approx 8 days ago. He is experiencing bad kidney pain, yet urine is clear. He has no swelling and his scrotum is not painful. He is now complaining of being freezing cold, however his temp is 36.6 deg C. He is also c/o very bad headache. He looks unwell, bp is 159/95, he normally has normal blood pressure. He also has right sided chest pain , however does have GORD. What might be going on?
