Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain if your wife has got
sunburn on lips which led to
redness, swelling and soreness that has not yet resolved, the reason might be as she has not taken any treatment to reduce inflammation or there can be persistent irritation to lips by either sun exposure or any other form of heat or
allergic reaction to some lip cosmetics or any food or medicine..
You should
consult a dermatologist and get evaluated and he can advise you to take a course of
Steroids, Anti-inflammatory medicines, antihistamines/anti-allergics.
Local application of steroid ointment can help..
Doing cold compresses can reduce inflammation and soreness..
Avoid sun exposure and if exposed always apply a SPF 15 containing lip balm..
Hope this information helps..
Thanks and regards.
Dr.Honey Nandwani Arora..
