chicken-like skin

Hi, I have this chicken-like skin in my arms and legs. Sometimes its itchy, but I realize is that the chicken-like skin is spreading. I don't know where I got it but probably its from the medicine that I take. Maybe you can help me how to cure it. I would like to inform you that I'm allergic to antibiotics.

Hi, welcome to the forum. The first thing to be ruled out is Drug eruption, and whether you have taken any drug recently as it involves 75% of cases. Few of the drugs are known to cause such spots all over the body. This can be seen within 2 weeks of exposure esp. after second dose due to sensitization. The most commonly prescribed medications (eg, antibiotics, sulfa) are implicated often.

If not drug, other allergens should be identified like certain food (fish, mushrooms etc.). Once the factor is identified then further exposure to the allergen should be avoided.
In such cases antihistaminic and steroids against prescription are quite effective.

Other possibilities needed to be ruled out are viral exanthem, Mycoplasma pneumoniae - serological test and chest radiography is important to rule out and should be treated with appropriate antibiotic, Rocky Mountain spotted fever (it is tick borne disease and needs serological test for diagnosis), infectious mononucleosis, scarlet fever; as a result of streptococcal tonsillopharyngitis, Kawasaki disease, and dengue. Hence, you need to undergo serological tests for few common causes.

I suggest you to consult physician for detailed evaluation. Take care and regards.
