hi,
It seems that you are having chelitis..
There are many causes.
Irritation,allergy,drugs,sun exposure,stress,tension,
anaemia,vitamin deficiencies,nutrional deficiencies,internal diseases..etc
You
consult dermatologist, have investigations to find out some cause.
Take treatment of disease which is responsible.
Avoid sun exposure.
Avoid tension and worries.
mild steroid with antibiotics cream may be helpful.
Folic acid,
steroids in tapperind dose,iron,antihistaminics may be taken.
I hope you got my answer.
Thanks.
