👉 Hematoids are a type of blood clot that occurs in the veins, causing pain and discomfort. They can be caused by several factors such as trauma, bleeding from surgeries or procedures, or certain medications. The symptoms of a hematoid include swelling in the area around the vein, redness, pain, and sometimes pus or fever. Treatment may involve antibiotics to treat the infection, but it is important to seek medical advice before taking any medication.
