Please help Personal question

The other night I was with a so called friend at home. We were having Christmas drinks. He proceeded to make mine double scotches. During the night I had two heavy falls. Blackening my eye and hurting my ribs. I also hurt my head and don't know if I blacked out. I suspect I did as we did not eat and I ended up in extreme pain. I went to the local hospital and was given some painkillers but they did not call the doctor and advised me to have an XRay next day. I returned the next day and saw a locum doctor as I was concerned about the painful ribs.She didn't take an X Ray as she felt it might just be ribs which hurt and put the visit down to situational crisis counselling as there were other serious issues involved. I did not want to go into these now. I thought drinks might be spiked. I rang drugs, and alcohol as I usually get so sick with hangover if I overindulge, but no vomiting, no headache or diarrhoea. Apparently people who don't normally get hungover vom & dia, do if they have drinks spiked. I still have very sore side and pain under the left breastbone, sore head. What worries me also is that when I urinate I usually pass at least a cup about eight times a day. I have only been passing small amounts. I am just scared there could be something underlying that is not apparent in the mirroe and I seemed dizzier two days after fall. I feel I should go back to doctors just to ensure all well. Any advice appreciated. I have given this person a piece of my mind and I am angry at myself as I should have seen it coming.
