Dr. Theodore Warkentin, professor of pathology and molecular medicine at McMaster University and a co-author of one of the recent papers says that vaccinated patients must aware of symptoms such as blurry vision, headache, weakness in their extremities, shortness of breath, chest pain, or unusual swelling in the arms and legs.
Cerebral venous sinus thrombosis is also known as CVST or a blood clot is very rare, according to scientists.
Sometimes a headache is the only symptom of CVST, but many patients have the following stroke-like symptoms:

- the person may not be able to lift both arms and keep them there because of weakness or numbness in 1 arm.
- their speech may be slurred or garbled, or the person may not be able to talk at all despite appearing to be awake; they may also have problems understanding what you’re saying to them.
