Oh dear !! I go for two months with no alcohol AT ALL, then I go to the doctor / hospital for tests on liver and kidneys, and get the "all clear" ....Great !! So I ask them about the terrible pain in my right lower back , and they suspect kidney "stones" . So off I go , "emergency admission" to Cheltenham Hospital, have a "scan" and am eventually told that it is PLEURISY !! No wonder it hurts so much ; I DARE NOT cough,burp, fart,or (worst of all ) sneeze, without suffering SEARING AGONY !! Let us hope the various antibiotics and painkillers ( I had some last week that you shove up your arse / ass ) and they were embarrassing but effective ! Wish me luck !!
