I have white patches on both knees and elbows and have taken medical treatment for 3 months but still it seems increasing. Tab.vitibex 2 times a day and melgain lotion 2 times a day on diet of sour and spicy foods.

It seems like you're being treated for vitiligo, a condition causing white patches. Despite 3 months of treatment, the patches are increasing. Concerns with your current treatment and diet: 1. *Treatment duration*: 3 months might not be sufficient for noticeable improvement. 2. *Diet*: Consuming sour and spicy foods may exacerbate vitiligo symptoms. Consider avoiding or reducing these foods. 3. *Sun protection*: Are you using sunscreen with at least SPF 30 daily? Recommendations: 1. *Consult your doctor*: Discuss your concerns and the increasing patches. 2. *Dietary changes*: Consider a balanced diet rich in antioxidants, vitamins, and minerals. 3. *Sun protection*: Ensure you're using adequate sunscreen and protective clothing. 4. *Alternative treatments*: Your doctor may suggest other options, such as phototherapy or immunomodulators. Schedule a follow-up appointment with your doctor to reassess your treatment plan.
