We have been through quite an ordeal the past two weeks with my son. To give you a small bit of background he fell over on a Saturday and had a few scrapes on his arms. At this point we didn't think this was at all related. A day later he came to me in the night sweating a bit confused classic flu symptoms after staying with me for the night when we awoke he was still the same but with 3 great big red hot rashes on his arms. We phoned 111 who sent an ambulance straight away they checked his obs he had high heart rate, low blood pressure and a temp of just over 40! They though it could be sepsis and rushed him in the doctors at a&e promptly diagnosed cellulitis and said at worst a couple days in hospital with IV antibiotics he'd be fine. Fast forward 2 days temp was still the same rashes getting worse hard underneath. They where actually quite worried about him. Dermotology came to see him and this very abrupt (not peads doctor) came to see him took one look said the diagnoses was all wrong said loads of big words said this was making him really ill and we needs scenes and tests and possibly surgery and went of with his team. The nurse later told him off for his abruptness they sent him for an MRI just when they where about to scan his other arm (to compare I believe) they said the ward wanted him back they said he was going to surgery now! Even though he had eaten only 5 hours ago and had a temp they worked him of and explained that the bacteria was eating away at his tissues! And that they have to cut it away and possibly do other things to his arm. And he could be left with a dip in his arm. Luckily this didn't happen and surgery went well he went back to surgery 2 days later to have everything re washed and looked at. He spen 4 days in high dependency and was diagnosed with the VERY rare necrotizing fasciitis he stared to fell better and got moved onto general ward bit then 2 days ago the patch under one of the infected places became hot and hard so they worked him back of to theatre everything was fine. But it raised the question for me when he is discharged (hopefully tommrow) do I have to look out for it returning I did ask doctors and they said it probably won't but this wasn't the consultant we were dealing with who I asked I guess I wanted to ask mumsnetters opinions and also share my story thanks for reading.
