Thankyou Dr. Sharma, I'm going to make an appointment with my neurologist and probably a dermatologist also just to be safe.
Hi there. The lumps could be unrelated to the concussion and be lipomas ,sebaceous cysts or folliculitis in the scalp. Since these are hard, these could be malignant also. A surgeon would need to examine these to conclude the cause and treat accordingly. Your neurologist needs to check you for the migraines as these again are unrelated to the injury. These are unilateral headaches associated with an aura like nausea, photophobia, and episodic. You would need to avoid the triggers that cause these headaches and take certain medicines which can prevent the attacks and can treat them. An MRI head needs to be done for revaluation of the concussion.Hope this helps.
