Which of the following symptoms can be caused by paresthesia?

Paresthesia refers to an abnormal sensation in the skin, often described as tingling, prickling, or numbness. It can occur when nerves are damaged, irritated, or compressed. In the context of paresthesia, the primary symptoms that can manifest include numbness, which is a direct result of nerve disruption.

Additionally, while paresthesia typically presents as a loss of sensation or a tingling feeling, it can also lead to pain. This pain may not be typical, as it often manifests as neuropathic pain, which is distinct from nociceptive pain that arises from tissue damage. In some cases, swelling can accompany paresthesia, particularly if the underlying cause involves inflammation or compression of the nerves, although swelling is not a direct symptom of paresthesia itself.

Since paresthesia can encompass a range of sensations including numbness and pain, and may be associated with swelling in certain situations, the correct answer encompasses all these potential symptoms. Thus, the inclusion of numbness, pain, and swelling as possible symptoms effectively reflects the complex nature of nerve-related issues that can arise in various conditions.
