Is my inflamed, itchy rash infected?

It appears that you are experiencing symptoms of oral thrush, a condition that causes your tongue to be covered in white. Smoking is one of the major causes of this disease, and so is drinking alcohol or having a weak immune system. The most effective way to deal with it is to reduce smoking and alcohol intake, as well as maintain good oral hygiene. Additionally, drinking more water can also help.

Tinea versicolor can be treated with antifungal creams. Please apply it to the affected area twice a day for 2 weeks. If you don't see any improvement, please try oral antifungal. Also, keep the area dry and clean and avoid wearing tight clothes as this can make the affected area sweaty. If the problem does not go away still, please consult a doctor for the same. 

Dermaplaning is helpful in decreasing wrinkles, acne and fine lines. But to know whether you are eligible or not for it, you need to visit a dermatologist. Based on your skin type and condition, the doctor will tell whether dermaplaning is suitable for you or not. And talking about the cost, it depends on the area that needs treatment and it also depends on the doctor and the clinic. 

You may have­ little bumps in your mouth. They might be canke­r sores, common issues that often he­al themselves. Eating and spe­aking could feel uncomfortable due­ to the bumps. Reasons could include stre­ss, injury, or certain foods you've eate­n. Try rinsing your mouth with salt water or using over-the-counte­r gels to ease the­ pain from bumps. Avoid spicy, acidic foods that can irritate them further.
