Severe shoulder pain after drinking alcohol-extreme pain until alcohol (which is only a couple of drinks) is out of system at 5 or 6am, no relief or worsening of pain on movement of arm. No relief from painkiller or anti-inflammatory tablets. Occasional dizziness, blurred vision, ankle swelling-all mild & ignorable. Unexplained weight loss- 1 to 2lbs per week for 1 year. Long term rash on upper outer arms & on shoulder blade area for 6 months. Never itchy - dry rash & burns if any creams etc applied. Initially looks like large area of ringworm in different sizes but now looks like a general patchy rash. Comes in waves with circles first, then patchy, back to circles, then patchy again etc. Doctor insisted it isn t fungal. Low bicarbonate levels of 19, high chloride levels of 109. Low folate levels of 2.5, now on prescribed folic acid. NRBCs 0.01 on differential blood count. Awaiting coeliac screen blood test. Hypothyroidism for 5 years, levels all ok at present. Not a diabetic. Any advice appreciated.
