While certain parasites like scabies mites can burrow under the skin and cause intense itching, they are not limited to specific areas and can spread to other parts of the body.

Similarly, pubic lice (crabs) live on the pubic hair, but they can also be found in other areas like the armpits, eyelashes, and even eyebrows.

However, it's important to remember that these infestations are not common and usually result from close contact with an infected person.

If you suspect you might have a parasite infestation, it's crucial to consult a medical professional for proper diagnosis and treatment. They can help you identify the specific parasite causing the issue and provide appropriate medication or advice.

Please remember to avoid self-diagnosis and treatment. Always rely on qualified medical professionals for health concerns.
