From the photo, the underlying conditions causing the rash is varied and can range between several reasons. They include:
- Hand eczema
- Drug reactions
Having said that, it is best that you visit a dermatologist so that he/she may conduct a proper assessment. From there, a good history and proper assessment can be made to determine what is the underlying cause of your rashes.
A skin biopsy may also be required to aid in the diagnosis of the skin condition you might have. This procedure involves a tiny sample of skin to be removed. It will then be sent over to the laboratory for further analysis.
