Tics can be classified as motor or vocal. Motor tics are associated with movements, while vocal tics are associated with sound. Tics can also be categorized as simple or complex. Simple motor tics involve only a few muscles usually restricted to a specific body part. They can be clonic (abrupt in onset and rapid), tonic (isometric contraction of the involved body part) or dystonic (sustained abnormal posture).
Bed bug bites are not initially painful and can go unnoticed for hours or days. This allows bed bugs to withdraw human blood for up to 10 minutes with each feeding. Bed bug bites occur most commonly on exposed skin, such as the upper body, neck, arms and shoulders. Bite Symptoms.
The bites are not dangerous, but might itch. They can be found as single bites, in lines or clusters on exposed skin areas such as the legs, arms and neck. It is rare for a bedbug to bite the face or bottoms of the feet. Bed bug bites will heal on their own in 3 to 5 days if left alone. If scratched, infections can form. Bite reactions can vary from episode to episode with some people seeing an increased reaction, while others may see a smaller reaction. These insects do not transmit disease to humans.
