I have found walk in centres are worse than useless, we have one about 6 miles away at the local hospital opening hours 8am to 8pm Monday to Friday during the summer only. Same with its A&E unit.
The one at the local heath centre is the same but is open all year round.
The next nearest is at the main hospital 11 miles away in the A&E unit, I'm not sure of the hours, but as the out of hours Dr's run it you can wait in there for hours if the dr has been called out.
My experience there went like this, I managed to scrape up a large flap of skin on my right shin, I carefully wrapped it in cling film with the flap closed over the wound, now as a prolific bleeder I then wrapped a couple of clean tea towels round it to contain any blood, I arrived at the walk in centre and told the nurse at the desk what I had done, I also told her I was diabetic and on blood thinners, she said take a seat the triage nurse will be with you shortly, 15 mins later the triage nurse took off the towels and cling film allowing a lot of blood to escape and pulled back the bit of skin and left it open, she said wait here the dr needs to see this before I can stitch it,
So 1 hr later the skin is curling up, I'm still bleeding over the floor and my numbers have plummeted to 2-5, my son the went to get me a coke to up my numbers, the nurse says I can't have anything till I've seen the dr, I tell her I'm hypoing and she says why didn't I tell her I was diabetic, a row ensues as I reminded her I had and she had it on the screen I was diabetic on thinners, she then says I should be in A&E across the hall.
So over the hall we go and of course by then, the flap of skin that could have been stitched back has well and truly died so I had to have a piece of plastic skin put on with sterri strips and the healing time was 18 months instead of a few weeks.and endless visits to the nurse at the drs every other day to have the dressing changed,
I now have a huge brown scar on the front of my leg that is not only ugly but has the weirdest sensation when touched, it also has perpetual flaky skin that no amount of moisturising seems to fix.
I still think if you have high numbers and an infection at a injection site, and you are unable to see your own dr the best place is A&E, as I have been told that ketoacidosis is a killer, and with the high numbers and infection that is a possibility, of course I could be wrong but I wouldn't like to take the risk.
