My Hb started having a really bad burning sensation, wanting to urinate but just couldn't. He went to GP Out of hours, but when he got home he placed a tablet on the table and said that's for you to take. I didn't understand and ask why's is it for me? He said doctor thinks you need to take it. Again why, what's it for? I asked. An infection, doctor thinks you may have given me an infection. I felt numb, I had no symptoms! Had my Hb cheated on me? I asked what infection? He said just take it. There was no leaflet. I have no idea what it was. Could it have been a bacterial infection. He's plumber, could he have picked something up from someone's toilet, blocked sink. Or do you thinks he's cheated and that tablet was for an Std? It was one single quite large tablet.
