I have spots appearing all over my back around 3 centimeters apart, started like hives that turned into itchy fluid filled vesicles, red all around edge, scratching took top off which made the spot sting and look like little ulcers, this has also occurred on my legs 4 times but smaller, one on my finger and now 3 forming on my chest, also back of neck but only separate spots 2 to report on neck, one on side of neck also, my roof of mouth is yellowy there is no growth of yeast just the hue of yellow, the spots crust over then scab blood tops, lasting days? I have recently been in hospital 2 weeks ago with severe kidney infection I was on 3 types of antibiotics to clear the infection took 6 days to clear, in this time I had several nights of 38.1 °c temp and hot sweats and freezing cold shivers but I was hot still and had the same 38.1 temp I was released from hospital and put on a 4 days antibiotic treatment, I had a WCC of 14 .6 and a CRP of 130 in hospital.
