Skin Neutralisation Treatment is available in the UK. I would contact clinics. Just google it, there's a few that offer it. It's the treatment that is supposed to be aimed at conditions such as yours.
Any advice I give is just that, from an educational background, I'm not a doctor.
Also, I would contact Linenup on the forum, he's full of great advice.
Allergy medical.uk. Have plenty to say on the neutralisation treatment. It's given by qualified nurses.
Also, have you been allocated a specialist or professor who deals with dysbiosis within the NHS? Are you aware that there are properly trained persons including dietitians in dysbiosis within the NHS, I'm not just talking Sibo, I mean gut dysbiosis from the large bowel travelling upwards to the small intestine up into the stomach upwards to the mouth and nose, are you aware that there are professionals you should be assigned under. These can be hospitals with Universities linked to them.
