Welcome to HCM.
As informed by the doctor it is in more favor of simple headache than anything else. IF the headache is affecting your daily activity i advice to take over the counter headache relieving medication.
Blood near the tip may be due to the minor local trauma and as they have examined i dont think you need to worry much.
It will be better if you go for complete picture, it will help in excluding anemia
If the symptom persists i advice you to see physician with the reports for further help.
Hope I have provided the information you needed.
Wish you good health. Take care.
