Which tabs treat my fungal infection effectively?

Stress, neglecting oral hygiene, and certain foods can cause mouth ulcers. Usually, Omeprazole tablets are not used for the treatment of mouth ulcers as they mainly aid with stomach issues. For the treatment of ulcers, you can use over-the-counter remedies such as oral gels or rinses to reduce the pain and facilitate the healing process. Do not forget to maintain a proper dental hygiene routine and a balanced diet to keep them from returning. 

Sometimes not having enough vitamin D3 can cause people to lose their hair. You should keep taking the vitamin D supplement as the doctor told you. You should try to eat more foods that have iron and protein in them as well. One thing that might help is finding ways to relax when you are stressed. 

You likely have a fungus on your testicle. The symptoms you have mentioned like the peeling of skin, white substance, and smell, along with itching, appear to be a normal fungal infection. They may be caused by the lack of hygiene or tight clothes. This can be solved by keeping a dry and clean environment, wearing loose clothes, and using a pharmacist-recommended antifungal cream.

You have a fungal infection in your private area. Sometimes it can be due to sweat, tight clothing, or not drying properly after a shower. The main symptom is the itch and the redness. This can be treated with antifungal cream. Keep the area clean and dry. Loose-fitting cotton underwear and not scratching the area will make it better.
