<s>[INST] I have a small lump in the lower back of my head. It's been a week since I got it and I have a headache all day. I get very dizzy when I get up from sitting or laying down. I get very nauseous and I've lost my appetite I have a docs appt tomorrow, but do you have any info or suggestions? [/INST] Hi.The lump and the other symptoms looks to be no related to each other. The first : small lump in the scalp can be a boil only.The other symptoms cane be due to vertigo due to affection of the internal ear or cervical spondilitis and so on. Your Doctor can tell the exact diagnosis as you need a clinical examination and investigations like MRI . </s>
