This is for my wife, Last week she got fever and bulge her lower lip and last tooth. Then we met a doctor ,he told this is due to viral fever and bacterial attack from last tooth. suggested to test blood .The result shows esr 40 and vrs16 and all other tests are normal level.then treatment started for reducing the fever and bacterial infection. Now two week finished ,no fever and pain ,but lip wound not completely recovered. doctor said it may take another 2 weeks to come in normal stage ,and after that he recommended for more investigations including biopsy (skin). we are too much worried . Why esr level is increased ? Is any major test required ?
