Ferritin is a protein that stores iron in the body, and a ferritin test is used to measure the amount of ferritin in the blood. Low ferritin levels can indicate iron deficiency, while high levels can indicate iron overload or other medical conditions.

Weird sensations after a ferritin test could be due to a number of reasons, and it’s best to consult with a healthcare professional for an accurate diagnosis. Some possible reasons could include anxiety or stress related to the test itself, or a reaction to the needle used to draw the blood. If the test results indicate abnormal ferritin levels, it could also be a symptom of an underlying medical condition. It’s important to discuss any concerns or symptoms with a healthcare professional for appropriate evaluation and treatment.
