For two months daily. pains on top of head. it happens on the left side mainly, but has also happened on the right. sometimes a sharp pain, or dull ache. crawling sensation/tingling on head. concerned about brain tumour?

Doubt it' brain tumo: Headaches are very common in otherwise healthy people. Brain tumor is an uncommon cause, so I would put it as the least likely cause of your headache unless it is progressively getting worse. Common causes are tension headache and migraine. Both are made worse by stress. Try relaxing exercise like a walking daily. If the headache is presenting you from functioning, take paracetamol and let us know

Headaches: Sounds like a pattern of chronic daily headaches and would consider a migraine management approach. Preventative medication can abort the pattern and turn this around. You could do a virtual consult with doctors in UK, or we here at HT could accommodate via our paid site.

Head tingling : See a doctor in person. This does not sound like a tumor. I am thinking of a nerve problem in the neck. Look up occipital neuralgia.

Get evaluated.: I believe you have socialized medicine in the United Kingdom, which should allow you easily to see a health care provider. Allow them to evaluate you. Doesn't sound like a tumor, could be migraines or stress, either way see a provider.
