- Nerve-related disorders
- Diabetes-related nerve damage
- Multiple sclerosis
- Pinched nerves
Nervous system conditions can sometimes create itching sensations even when the skin appears completely normal.
6. Itchy Underarms
Occasional underarm itching is usually harmless and often results from sweating, shaving, or irritation from deodorants.
However, persistent itching accompanied by swelling or enlarged lymph nodes may require medical attention. Certain lymphatic cancers, including lymphoma, have been associated with unexplained itching in the underarm area.
7. Itching Accompanied by Yellowing of the Skin
When itching occurs together with yellow skin or eyes, the problem may involve the liver or bile ducts.
Conditions that can produce both symptoms include:
- Hepatitis
- Cirrhosis
- Bile duct obstruction
- Other liver disorders
Healthcare providers often consider this combination of symptoms an important warning sign that should not be ignored.
8. Itching Alongside Unexplained Weight Loss
Persistent itching combined with unexplained weight loss, fatigue, fever, or night sweats may indicate a more serious underlying condition.
