Is this a tick bite?

Symptoms usually are marked by losing a heavier amount of hair or thinning patches. One way you can try is to take vitamin-rich food such as biotin and minerals such as zinc, through a balanced diet. Gentle hair care practices, as well as abstaining from strong chemicals, can also make a difference. Nevertheless, seeking medical advice cannot be avoided to determine what exactly requires the intervention and to be offered the right care (therapy). 

It seems you have several health issues. All these might be connected with different things. The reason for the bad smell on the skin may be due to sweat or bacteria. Dry skin or a fungus can cause dandruff. Cavity comes from eating sugary food. Back pain could come from bad posture; stomach trouble could be caused by what you eat or stress. Also having an appendix problem may make it hurt when you use the toilet.

Your skin is giving you a lot of trouble such as clogged pores, uneven pigmentation, acne, acne scars, and dullness. These may be caused by bacteria, the shedding of dead skin cells, and inflammation. You can try using a gentle cleanser, products that respect the skin barrier, medications that contain salicylic acid or benzoyl peroxide, and sun protection.

You may have a condition called night sweats which might contribute to the effect of various factors, including anxiety, hormonal changes, or infections. Firstly, try to keep the room cool and comfortable at night, wear light pajamas, and don't consume caffeine before sleeping. In the morning, take clear water as much as your body can accommodate; this will keep the hydrated fluid in your body.
