Had a cough for 4 weeks and persistent fever - about 38oC. Went to the docs and he took bloods. Had one lot of antibiotics already. Got told I'd likely to need to go for an X-ray. Blood result came up with erythrocytes sedimentation rate value of 80 when it should be 15. It's a crude test but means some inflammation somewhere. Had my X-ray which had some bits in left lobe - mainly due to infection but A and E sent me home with clarithromycin to mop up any other bugs as he said no point in staying in hospital all weekend and if feeling no better, Monday to go back. He said there's no chest specialists on over the weekend and he was just a general doctor. My temp was ok this morning but is steadily creeping up and am feeling a bit tired again. Anybody had anything similar? Really worried there is something underlying? Anyone had an ESR of that and if so, what was the cause?
