Just been to walk in with DS 14 he has an infection in his upper arm doctor put him on anti bs three days ago. Seemed to be going well until last night he woke up this morning and has a 6x3 cm space of red and it has gone hard so took him to walk in and they gave him a different Anti biotic. Most people would be happy with this, but DS has history twice this year he has had cellulites that hasn't got better and been prescribed a different antibiotic. Two months ago this happened he ended up in A&E a week later had two operations and developed Sepsis it was the worst two months of my life. The same happened four months previously but with only one operation and no Sepsis. I thought it needed draining before it got worse. I just cant stop thinking about what happened last time. Any advice or am i just over reacting. Its spread today as well.
