Hi,
Thank you for posting your query.
I have noted your symptoms and it seems that you have developed a scalp 
hematoma (collection of blood underneath the skin over head). This is responsible for your 
headaches and nausea.
You would benefit from symptomatic treatment with 
ibuprofen tablets (for headache) and 
ondansetron tablets (for nausea). 
If symptoms persist, it may be better to get a CT scan of brain done and 
consult a neurologist.
I hope my answer helps. Please get back if you have any follow up queries or if you require any additional information.
Wishing you good health,
