It just indicates that you likely had an infection, but you knew that already with the needed antibiotics.
Thank you for your help. I forgot to mention that I have had a slight temperature too. 37.5C.
Is this of any relevance?
Yes, the antibiotics will greatly affect things, but they should have been resolved by now. Touch base with the doctors so that they know what's up. We don't know your other medical conditions, but some other underlying condition may still be in play here.
