I am being colonised by a fungal infection

Yet another one voting scabies...its intensely itching as the mites are burrowing under the skin.

Yes I have heard of a few people with scabies lately.

Optimise your Vitamin D level will help with fungal infection

You might need help applying to your back or use on of those bath/shower loofah sponges with a stick. You want to cover you whole body from neck down. Best of luck OP. Really shitty thing to happen.

I am a pharmacist. Once as a student in Australia a Dr came in. He had contracted scabies from an overseas patient (it is very contagious so suprised your DH hasn't got it). He used a lotion Benzyl Benzoate. You literally apply it all over from the neck down. It is very strong and handy for treatment resistant scabies. Paint more, on the badly affected areas. You apply it once. wait then rinse off in the shower. Have you seen on Google how scabies presents as others have said in crevices like between thumb and forefinger. Little dots. Also as pp said the hydrocortisone will only be temporarily reducing the itch as it is anti inflammatory. Not a long term fix. I would compare photos of the rash to Google images if similar use the option I mentioned that should fix it although how you contracted it is a mystery this dr had been in contact with a patient recently returned from India.

Hands you tried propolis balm (bee product). I think it's anti fungal as well as anti bacterial. It's very good stuff.

Sounds more like scabies

But it could be scabies. It spreads rapidly in care settings. It also takes 4-6 weeks for rash to appear so may not be from nursery. If you’ve travelled abroad recently or stayed in a hotel recently that may be your source.

Have you changed your washing powder or soap recently. With the location of the rash it could be dermatitis. It seems to be where clothing is in contact with skin and may get damp, armpits groin and feet/socks.
I have an SLS and sodium benzoate allergy ( found in a lot of detergents). In the summer I double wash clothing, first with detergent then without so it rinses out as much detergent as possible.
Manufacturers can change formulas from time to time so even if you haven’t changed brand you can still have a reaction. Possibly changing to a hotter wash cycle may be helping inadvertently because it may remove the detergent more effectively.

Colonisation is also medical and scientific terminology.

And there was just no other way of phrasing this, for sure.
I know people do not give a flying fuck at all, but here is the definition of a colony: A territory that lies outside of a heartland. But the heartland still controls it, for economic reasons mostly.

Put some sulfur cream on that shit and don't write essays about your groin, woman. Showering twice daily also wrecks your skin barrier, do it only once.

I'm sensitive to antifungals plus they don't work well for me, but amazon sell an amazing herbal antifungal cream that heals anything like that within a day or two. I always keep it to hand just in case and I've never had an adverse reaction from it, despite being sensitive to many creams and medicines. it's expensive but spreads well so you don't need much.

ETA link isn't working. it's called Antifungal Cream for Scalp & Body Skin: Suitable for Athletes Foot, Ringworm, Jock Itch, Tinea Versicolor & Seborrheic Dermatitis, Gentle and Effective Plant-Based Formula 20g
Brand: Kopa Haiku

Weird tip but put socks on before underwear otherwise you pull the fungus from your feet up your body. Wash at 60, towels after every use. Anti fungal talc after bathing. Try to avoid deodorant. Antifungal cream daily and I find aloe Vera helps soothe the itch.

I think it's scabies too.

Google "scabies in an infant" and look at the pictures. Commonly affects soles of feet and palms of hands/face in an infant which fits with you thinking foot and mouth.

Scabies can be missed even by professionals.

If you are prescribed a treatment make sure age is taken into account for your child with what is suitable.

You could have a look at the "ink burrow test" too.

Last week vs today

I’ve had some kind of ringworm/fungal infection on my inner thigh for the first time in my life (I’m 37!) after a birthday spa day in October. No cream the doctor gave me helped. I sympathise with the itch it’s horrendous. I was at my wits end. My old school dad said have I tried iodine. I didn’t think it would work but out of desperation ordered some in little like Q tips from Amazon. A week later and it’s started to clear up!!

Whaaat the hell??? I'm shocked!

I wouldn’t use dakacort or trimovate as they contain steroid, which masks the fungal infection but it comes back stronger.

Id wash it daily with Nizoral treatment wash and put Lamisil once a day on it.

Please ask doctor to test for candida auris. They won’t know what that is probably so you’ll have to tell them, but it’s important you get this looked at soon as possible. It’s an emerging treatment resistant fungus but I know of people with it through my work in healthcare. It can infect your insides too so you’d need to have antifungals via a drip not just topically xx

I do feel for you OP.
Obviously, see your doctor and take their advice, but as a long term thrush sufferer (in the past thankfully), I just have a couple of things to add:

1. Get your iron/B12 levels etc. checked as previous posters have suggested
2. Cut down on sugar
3. I never (quite) got to the point of ordering this as Canesten worked for me, but there are great reviews out there for Mama Nature thrush treatment. Maybe worth a go?

It totally sounds like scabies, there’s a huge outbreak at the moment. Get some lycette cream for the whole family. Hydrocortisone really helps with the itching. Wash everything at 60, or quarantine it for 3-7 days. Honestly, my money is on scabies.

Daktokort is great for this type of thing. Can take a few weeks

Definitely Try Nizoral shampoo as a body wash. My son has a rash that was spreading on his legs - tried a few creams with no joy but it cleared up a week or so after using Nizoral alongside the creams

I had a similar effect on cutting all sugar and drastically reduced carbs. Cleared my resistant recurring infections and my skin was transformed too.

I didn't have the patience to wait for supplements, I just needed to get it sorted and feel better in myself. So I had an infusion at the Iron Clinic through my health insurance. A ferretin level below 30 is sufficient to justify an infusion medically, regardless of anaemia, albeit the NHS don't give them easily.

I would ask your GP to check iron, ferretin, B12, vitamin D as a starting point.
