Hi Goldy
This is a mystery! Please know that I am not a doctor so I cannot give you any medical advice.
Here is an article about how to tell if it is a rash or skin allergies which may help.
It seems if you were diagnosed with contact dermatitis then this is allergy based and so you have to figure out what you are coming into contact with...which is causing this reaction.
The National Institutes of Health give us this information:
"Common allergens associated with contact dermatitis include:
* Poison ivy, poison oak, poison sumac
* Other plants
* Nickel or other metals
* Medications
o Antibiotics, especially those applied to the surface of the skin (topical)
o Topical anesthetics
o Other medications
* Rubber or latex
* Cosmetics
* Fabrics and clothing
* Detergents
* Solvents
* Adhesives
* Fragrances, perfumes
* Other chemicals and substances
Contact dermatitis may involve a reaction to a substance that you are exposed to, or use repeatedly. Although there may be no initial reaction, regular use (for example, nail polish remover, preservatives in contact lens solutions, or repeated contact with metals in earring posts and the metal backs of watches) can eventually cause cause sensitivity and reaction to the product.
Some products cause a reaction only when they contact the skin and are exposed to sunlight (photosensitivity). These include shaving lotions, sunscreens, sulfa ointments, some perfumes, coal tar products, and oil from the skin of a lime. A few airborne allergens, such as ragweed or insecticide spray, can cause contact dermatitis."
So do any of these things sound plausible for causing your skin reaction?
Not sure about candida causing this...that would definitely be a question for your doctor to answer.
Hope this helps some. Thank you for your question.
