[|Human|] For the past month I have had a lightheaded feeling that comes on especially when talking/laughing with people. I also have a mild but fairly persistant headache (for last week) and a stiff neck (pain on movement). Worried this may be sign of brain tumour or heart problem!?
[|AI|]  Hello, You have a light-headed, neck stiffness and headache these are not looking the symptoms of brain tumor because in brain tumor blurred vision, imbalance,strong headache, confusion and seizures but in some cases some symptoms disappears. But first tell me have you vertigo or pain radiation over left or right upper limb? It seems to me cervical nerve compression or cervical stenosis inspire of brain tumor or heart problem because due to the cervical nerve compression the patient feels heaviness on head, headache vertigo and sometimes numbness and pain radiation on either upper limb. Sometimes headache arise from neck joint problem. But also other causes of headache with neck stiffness as muscle strain or ligament sprain, cervical spine disorders, meningitis or other infection. But to rule out the exact cause get the X-ray and MRI.consult with Euro or or tho.
