Long story, so will be quick I have haemochromatosis which is high iron and having venesections to remove blood every 2 weeks, since this started in September I have had 2 colds, 1 chest infection, shingles, tonsillitis, sinusitis and now oral thrush which apparently is caused by a low immune system which mine appears to be. I have antibiotics and this horrible yellow glue like stuff for the thrush, like most people I am a bit anxious about health and as throat still dreadfully sore even though nearly finished antibiotics wondered if the thrush would cause a sore throat, roof of mouth also sore. Thought I would ask before I started to panic that it was something sinister.
