My DS cut his hand badly on glass a few years ago. I regret taking him to A&E since as a dentist I am perfectly capable of stitching a simple but deep hand lac, but since it was my son and glass was involved I thought it better to have it seen by “the experts”.
The “expert” turned out to be a junior doctor who had to you tube how to do it. Made a pigs ear out of the procedure resulting in the wound edges being rolled so when the sutures were removed it opened up. It then took weeks to heal properly leaving a nasty scar.
DS is quite proud of it, he reckons it makes him look hard.
At the time it was still Covid rules and since he was over 18 I wasn’t allowed in. Had I been with him I would have insisted on plastics being called out.
DS had been spiked, which is why he’d ended up with the injury. Was not really with it when it was being stitched but did find it amusing that the doctor had to find a friend for advice. The biggest failure was that they ignored it was a glass injury and didn’t do an X-ray to check for any glass shards in the wound.
You could also see all the tendons, in fact the first thing I did when I saw it was to get him to grip my hand.
What made matters worse was he was going to India on a cricket tour the day the sutures were removed.
Hindsight is a wonderful thing.
If I was you OP I would be on the way to fetch your DD and take her to your local A&E today.
My DS had cellulitis in his foot recently, he’s in Wales where the NHS is even worse than in England. It was easier for me to drive down with antibiotics than for him to wait in A&E or try to see his GP, so he could start treatment quickly before the infection spread further or he developed sepsis. Fortunately I have access to prescription only drugs via colleagues and friends.
