Severe Headpressure & Frequent Headache.

For the last 1 month, I have been having frequent headaches followed by vomiting, which last for 15–20 hours. I have had migraines for the past 7 years, usually once or twice a month, but during the last 1 year they have become more severe, especially in the last 1 month. I work in coding and spend long hours on a laptop. I consulted a neurologist last Friday, and he advised an MRI of the brain and whole spine, along with thyroid and Vitamin D blood tests. The blood test results and brain MRI reports are normal, but IMPRESSION MRI screening of the whole spine reveals  loss of normal cervical and lumbar lordosis  noted. A fairly large  T2Wt hyperintense cyst like lesion is noted in the  sacral  spinal canal region measuring 5.7 x 2.7 cm causing posterior scalloping of the S2 and S3 vertebral segments  suggestive of perineural cyst  causing mild  expansion of the sacral spinal canal region. Can this contribute to this headpressure and frequent headaches what to do next pls help.
