Facial Swelling
A cluster headache would lead to swelling on the affected side of your face. However, when it radiates to other parts, these areas can also become tender. This symptom occurs when the blood is pumped more and quickly due to the headache. Sometimes, it might be followed by facial sweating with perspiration on the attacked side of your face. The swollen areas make it hard to move your head or neck around. This eventually affects your normal activities. [4]
