Hi. Thanks for posting your concern at HCM Chicken pox at the age of 37 yrs warrants an oral antiviral e.g Acyclovir, because the risk of complications resulting from chicken pox is common in adults as compared to children. The rash of chicken pox would dry up/scab within a week or 10 days. For Acne you need to take an oral antibiotic/anti-inflammatory e.g doxycycline twice daily for 4-6 weeks. Topical antiacne preparations e.g clindamycin for day time application and benzoyl peroxide for night time application would be good enough for acne. Psoriasis is characterised by red, scaly patches on various body sites, specially extensors e.g knee, elbow, scalp etc All three conditions can co-exist in any one individual and are not responsible for each other. take care regards
