Health underwear is a kind of underwear specially designed and manufactured. They usually use some special materials or techniques to provide additional comfort and health benefits. However, even high-quality healthy underwear may not be suitable for everyone.

If you feel uncomfortable in some parts of your body after wearing healthy underwear, it may be related to the following factors:

1. The size is inappropriate: the size of healthy underwear is too small or too large, which may cause discomfort. Be sure to choose the right size to ensure comfort.

2. Material allergy: Some people may be allergic to the materials used in some healthy underwear. If you are allergic or sensitive to a substance, you may feel uncomfortable.

3. Design defects: Some healthy underwear may have design problems, such as unreasonable sewing or fixing devices. These problems may cause discomfort.

4. Personal habits: Some people may have different degrees of acceptance of a particular style, color or decoration. You may not be satisfied with some details, so you feel uncomfortable.

If you feel uncomfortable, I suggest you check the size first to make sure you are not allergic to the material of underwear. If the problem still exists, you can try to use other brands or styles of healthy underwear, or consult a professional.

It should be noted that everyone may feel different about healthy underwear, so this uncomfortable feeling is sometimes normal. If the situation persists or worsens, it is best to consult a doctor or a professional.
