[|Human|] I have a hard very painful to the touch, and painful when not touching knot on the right lower side of head.. And pea size painless lumps on back of neck.. A lot when I stand up vision blurrs completely out for a second and returns making me feel a little dizzy and nausious.. Please tell me what It could be!
[|AI|]  Hi, I understand your concern and would explain that your symptoms could be related to inflammation. The painful knot may be an infection or a cyst. I recommend consulting with your family doctor for a physical exam and some tests: - complete blood count- PCR- sedimentation rate for inflammation brain CT scan would help give more information on the knot and exclude possible intracranial lesions. Hope you will find this answer helpful. Let me know if I can assist you further. Best wishes,
