Thank you for posting your query.
The bump needs to be examined to establish its cause. It could be a spontaneous hematoma
(blood collection) or a benign tumor
such as lipoma. A clinical examination coupled with ultrasound
In any case, dizziness
seems to be unrelated to the bump.
Please get back if you require any additional information.
