[|Human|] I noticed a tender spot on the back lower left side of my head a few days ago.  It felt like I got hit.  This morning I noticed that I had a tender bump.  Tonight I found a couple more tender bumps.  They ache like I was hit or something. I am concerned about aneurysm or a tumor.  I have been under a lot of stress.  Today I felt sick to my stomach flu like symptoms.  I didnt realize I had to pay.  It doesnt state that when you first ask the question.  That should be upfront instead of getting someones hopes up!!!!!!!!!
[|AI|]  HelloThanks for writing to ChatDoctorYou need proper clinical examination and investigations. You have developed lesions in very short span of time, so tumor or aneurysm is unlikely. Since you are able to palpate it, it must be in superficial structure like bone or skin. It is tender, and it increases in number in one day, so infection is likely etiology. Better you consult neurologist. CT Scan can be done if needed. I think at present you need antibiotics and analgesics.Don't get so much stress. You will be alright. Get well soon.
