Hello and Welcome to ‘Ask A Doctor’ service.
I have reviewed your query and here is my advice.
If the lump hurts you visit ER & get examined, it can be a bony growth that needs medication or surgery. For headache take
Tylenol or
Ibuprofen. Since you have blocked nose &
cold, get X-Ray PNS done to rule out
sinusitis. Sometimes, chronic undetected, neglected sinusitis can get complicated because of infections entering into the brain tissues resulting in
abscess or inflammation of the intracranial blood vessels.
Take anti-histamines, Doxycyline, steam inhalation and Tylenol for relieve after physical examination. Get treated, get well.
Hope I have answered your query.
Let me know if I can assist you further.
