What are the different types of tactile hallucinations and their causes?

Tactile hallucinations are sensations that feel like something is touching or moving on the skin, even though nothing is there. These can happen for different reasons:

1. Drug-Induced Tactile Hallucinations: Some drugs can cause these feelings. This is not only from recreational drugs but also from certain medications. People might feel bugs crawling on their skin, a sensation sometimes called "formication."

2. Parkinson's Disease: People with Parkinson's disease might experience tactile hallucinations. This can be due to changes in the brain or as a side effect of the medications used to treat Parkinson's.

3. Delusion of Parasitosis: This is a mental health condition where people believe they are infested with bugs, leading to chronic tactile hallucinations. They might feel itching or crawling sensations on their skin.

If you or someone you know is experiencing these symptoms, it is important to seek help from a healthcare provider. For mental health concerns, you can visit 988lifeline.org.
