<s>[INST] I have a recurring rash on the tops if my feet, my legs below the knee, my arms below the elbow and the top if my chest. it is small red bumps and extreemly itchy. I have not used any new medications, soaps or lotions. I have been experiencing seasonal allergy symptoms, and am using cetirizine. I have been using this for about 4 weeks. any suggestions? [/INST] Hi, It is very vital to get this examined as it could be any of these: tinea/eczema/allergic dermatitis/psoriasis. Cetrizine will only reduce the symptom of itching temporarily. I suggest you visit the dermatologist for a thorough examination and proper medications for the same. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Smruti Pevekar, Dermatologist </s>
