hi, thank you for putting up your query on health car magic. as per your history, you have keloid on ches which is infected. sir, my treatment advise would be: 1. first of all, maintain hygiene as the infection needs to be controlled first. also, oral antibiotics needs to be started for 5-7 days and topical fusiderm or mupirocin cream twice a day. 2. for itching, you may take tab levocetrizine twice a day, and for pain, tab ibuprofen. 3. sir, once the infection subsides, since you dont want to take injections as they are painful, you may undergo surgical excision or ablative lasers such as nd:YAG laser, co2 laser etc or non ablative lasers such as pulse dye lasers after cosulting you dermatologist. 4. other treatment modalities could be intense pulsed light therapy, immunomodulators such as tacrolimus etc. consult a dermatologist nearby for effective tratment. wishing you good health. thank you.
