Hi,
How are you? What was the result of the previous ct scan? Increasing severity of headache is not good and may warrant further evaluation. If it has been 6 months and the headache keeps getting worse, it is best that you have this checked by your neurologist for proper evaluation. A new CT scan or MRI, to be compared to the previous scan, may also be indicated to help with the evaluation. Take care and do keep us posted.
Sorry for posting the same question twice, I thought one was going to Ask an Expert!
