Why do I get sudden bumps throughout the day?

Your piercing might cause some trouble. Sometimes, the hole on top of your skin may close up while the earring remains stuck from behind. This can happen when the skin wraps around the back of the earring. You might experience pain, redness, or swelling. To solve this, you can gently try pushing the earring out from the back or seek help from a professional piercer. Never force it out, as that can cause more harm.

A canker sore­ might trouble your mouth. They are small, round, and painful sore­s. Stress, spicy foods, or biting your cheek can cause­ them. Try over-the-counte­r rinses or gels to ease­ pain and speed healing. Soft foods are­ better; avoid spicy or acidic ones. Give­ it time - around one or two wee­ks - and it should disappear on its own.

The smoothening change is temporary. Your natural hair will come back in time. Speeding up the growth of your natural hair is possible by using nourishing hair products and avoiding further chemical treatments. Be a little patient, and then your natural hair will come back.

It might be that your underarms have become darker due to some other reason. So, it is best to consult an experienced dermatologist. The dermatologist may examine your condition to know the exact cause of it and determine a suitable treatment accordingly. 

I suggest that you visit a dermatologist and have them check out the mole on your nose. They can tell whether the mole is a benign or malignant one. However, based on the diagnosis, surgical removal or any other alternative mode of treatment may be recommended by a dermatologist. I suggest consulting a dermatologist near you for further advice. The treatment cost is determined by the recommendations and location of a particular clinic.
