Hi,
Noted the history of getting a hit on head, lump, pain,
neck pain.
It seems that the handle hit the area with a large
nerve in the
scalp causing
severe pain that got referred to the ear too.
The hit was sudden hence affected the neck too causing the neck pain.
The lump is obviously due to blood accumulated under the skin adding to the pain.
I would advise you the following in such a situation:
Apply ice on the affected area.
Take an anti-inflammatory medicine with painkiller properties like
Ibuprofen if it suits you.
Consult a Doctor to make sure the effects and get additional treatment as would be suggested and additional investigation as needed and advised.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. T. Chandrakant, General Surgeon
