What Causes Reddish Itchy Rash On Knuckle?
sounds like a fungal rash
Detailed Answer:
HI, thanks for using healthcare magic
Based on the description provided ( you can also attach a picture if you wish), it does sound like a fungal rash.
The steroid cream would have helped if it was related to allergic reaction in the skin and is also helpful in the initial treatment of fungal infections because they help to reduce the inflammatory response of the infection.
A topical anti fungal would be the best option. Fungi can sometimes have a slow response to treatment and it can sometimes be necessary to treat for up to 2 to 3 weeks.
Examples of topical anti fungals are: lamisil, nizoral, econazole, canesten, miconazole
If you are not using a disposable q tip or clothe to apply the cream, you should wash directly after to avoid spreading it to other areas.
Your local pharmacy should have one of these creams.
I hope this helps, feel free to ask any other questions
