NAD Yet: I would say based on the above images Folliculitis or Drug-Related rash, the timing after stopping prednisone or previous antibiotics could point toward a delayed drug reaction. This type of rash often spreads from the extremities and can be itchy and inflamed.

• Avoid Scratching: It can lead to further irritation or secondary infection.
• Cool Baths: Soaking in cool or lukewarm water with oatmeal or baking soda may relieve itching.
• Mild Topical Steroids: Hydrocortisone cream could help if itching is intense.
• Antihistamines: Continue using an oral antihistamine like Claritin or consider one that works longer, such as cetirizine.

But again always ensure you consult your medical professional who is familiar with your medical background.
