Welcome to the AMD forum!
The symptoms that you are having can be due to stomatitis. Irritation and fissuring in the corners of the lips
is termed angular stomatitis. It can also extend to lips and area around it resulting in swollen, reddened,
Most common causes are iron deficiency anemia, or vitamin B deficiencies. Try taking some iron supplements and
multivitamins for some days and see if the symptoms persist.
They can also be caused by allergies and infections. You could either be suffering from contact dermatitis or
from allergy to some food. You should get an allergy test done, either a skin test or RAST, to know what you
are allergic to. Contact dermatitis could be due to tooth pastes, mouth cleansers, spoons, cups, glasses, food
items, cosmetics, shampoos, etc, basically anything that comes in contact with your lips.
Another possibility is eczema. Herpes infection is another possibility if there is a history of kissing or
sexual contact (can get aggravated in presence of vitamin deficiencies, dry cracked lips, infections etc).
Cool moist compress, calamine lotion, oral anti histamines etc are helpful if allergy or dermatitis or eczema
is suspected. Taking a bland diet, not too hot and avoiding spicy food will help. If you can pinpoint what
started these symptoms, these home remedies may help.
The correct treatment will depend on the correct diagnosis. You can try the enumerated home remedies. If they
do not help, consult your PCP.
It is difficult to comment beyond this at this stage. Please let me know if there is any thing else and do
keep me posted. Take care!
