I am being colonised by a fungal infection

Oh and make sure none of the creams you are using contain urea. It's a common anti itch ingredient but fungus feeds off it - DHs joke itch exploded when he used it.

Try Eurax cream for the itchiness. It gives relief up to 10 hours and also try Piriton.

As an absolute chronic thrush sufferer, I'd:

1. cut sugar and carbs for 2 weeks
2. liberally douse the areas in vinegar (any vinegar will do) 4 times daily.
3. get your thyroid function tested.

1&2 massively helped me during flare ups and 3 finally solved the problem for good.

Very bad for your liver.

Second this. Please ask your doctor to do liver function test.

Short term the hydrocortizone in Daktacort will reduce the redness, so you won't know if it's working as an antifungal for a short while. Did your doctor take a swab?

I was going to suggest this. It's very strong, you have to dilute it otherwise you'll get chemical burns. The packaging says 1:10 oregano to carrier oil. I used an empty bottle and poured in a teaspoon of the oregano and then 10 of the carrier oil. The skin infection I had did finally go after using this 4 times a day, having tried both oral and topical antifungals to no avail.

Seconded.

I've not read all the replies but only the OPs.

Please stop co sleeping until you get this resolved. Do you have a bed you can take yourself off to and leave DD and DH?

You need to change your bedding every day. Same as towels.

There was a thread about scabies the other day and that family were having a nightmare so I hope it's not that.

I personally think you and your DD are unrelated illnesses and just a coincidence. DD is treated and getting better. Keep her separate from you.

Could you be having an allergic reaction?

In your situation I would be sleeping alone until you can get to the bottom of this. Separate beds, separate towels, fresh clothes.

Pityriasis rosea? I had that in my teens and it drove me demented. You're not "supposed" to get it in the areas you describe - groin, knees - but I did!

Try daktarin and a hydrocortisone mixed together. My husband had a weird rash on his armpit and this is what the Dr recommended. Took a few weeks to clear.

Have you tried a yeast free diet? I have eczema and went through an intolerance test. Been told to avoid yeast, mushrooms, cheese, grapes as these all contribute to itchy skin. Just wondering if that would help?

Not in this country but if you can get hold of a veterinary shampoo/skin dressing called Malaseb OTC somewhere in the world, it will be the answer to your prayers.

Also no carb/carnivore diet is good for fungal.

I would be giving major side eye to your immune system once it's in abeyance. You shouldn't be getting overwhelmed like this.

Have you tried bathing in Dead Sea salts. A podiatrist recommended it to me for athletes foot and it definitely helps sooth the rash, then dry thoroughly before applying the ointment

Have you tried taking a fluconazole capsule..one every 7 days for a few weeks

Haven't RTFT but any clothing which has come in contact with the infection, will carry the infection and spread spores to anything in your laundry drum. To kill the spores, everything has to either be washed at 60 degrees or washed in disinfectant or Halo sports detergent (most sports detergents aren't antifungal).

Will echo others that doing keto diet for a couple of weeks will likely help too, if you are getting desperate!

Sorry you are so itchy!

There are some products you can put in the washing machine that claim to get rid of fungas. AI says this:
Eradicil and Fongex are the leading, specialized antifungal laundry treatments in the UK, designed to kill fungi (athlete’s foot, thrush) and bacteria at low temperatures (30°C). They are used as a pre-wash or alongside regular detergent to prevent re-infection from bedding and clothing.

Maybe worth a go

Sounds like impetigo. My son had this and anti fungal creams make it worse. You need antibiotics if it is that. It is very contagious.

Personally, to eliminate all of the guessing, I would arrange an immediate private appointment with a Dermatologist. You could end up spending the appointment cost on a large number of recommended problems which do not help because you don't know what it is that is causing the issue and damaging your skin in the process.

It sounds terrible and I very much hope that you get it sorted out soon.

I'd also suggest looking at changing your diet. If continuous topical medications aren't working maybe something is going on internally

Yes, my GP put me on Griseofulvin, as the fungal infection was interacting with my psoriasis; and the fungal infection needed resolving from the inside out iyswim. It was very effective.

Also I would recommend regular showers with Hibiscrub or Hibiwash, and medicated powder.

Your immune system has gone crazy and all the medicated meds will lengthen the cycle as you’ve found. Try a basic cream like e45 and look at your diet…… it will feed off sugar and I’d be taking probiotics as well.

DH had something similar turned out it wasn’t fungal at all but eczema which flares from stress and poor diet.

What if you can't take the medication like this? I'm pretty sure I wouldn't be able to tolerate them.

It might offer some respite but it really won't help much. It won't resolve it, and it is unlikely to provide much relief.
