Hi doctor, after donating plasma yesterday, I noticed a red rash and small bumps on my arm, and now it seems to be spreading to my face and ears, possibly from me touching it. The bumps are small, like pimples, in a concentrated area, and theyre not leaking or oozing. Could this be a reaction to the iodine or nickel? Should I try creams at home, or is it better to see a doctor? We dont have health insurance, so Im hoping for some guidance on what to do next.

ears could be an allergic reaction to the iodine or nickel used during the plasma donation process.Possible Causes1. Iodine allergy: Iodine is commonly used to clean the skin before needle insertion. An allergic reaction to iodine can cause a rash, itching, and bumps.2. Nickel allergy: Nickel is sometimes used in medical equipment, and an allergy to nickel can cause contact dermatitis, leading to a rash, itching, and bumps.Next StepsConsidering you don't have health insurance, here are some steps you can take:1. Self-care: Apply cool compresses to the affected area to reduce itching and inflammation. You can also try over-the-counter (OTC) hydrocortisone cream or calamine lotion to help soothe the skin.2. Monitor symptoms: Keep an eye on the rash and bumps. If they worsen, spread, or become severely itchy, seek medical attention.3. Contact the plasma donation center: Reach out to the plasma donation center where you donated and inform them about the reaction. They may be able to provide guidance or offer to cover medical expenses related to the reaction.When to Seek Medical AttentionIf you experience any of the following, seek medical attention:1. Severe symptoms: If the rash, itching, or bumps become severe, or if you experience difficulty breathing, rapid heartbeat, or dizziness.2. Infection signs: If you notice signs of infection, such as increased redness, swelling, warmth, or pus.3. Worsening symptoms: If your symptoms worsen or don't improve with self-care.
