Hi, I am suffering from headaches for the last 4 months, in the back of the head and temples, at times also in the eyes. I have a history of low back surgery in 1991 and also developed some hernias in the intervertebral disks in the upper back. In the last 4-5 months I also had multiple periods of depression, never longer than 4 days, when I feel alien to my family and life loses any color or sense, also getting very sensitive to loud sounds, avoid talking and stay away from people and sources of noise. I am wondering if the herniated disks in my spine can cause increased intracranial pressure, which in tern causes the headache/depression combination. I am 53, and never had similar problem, not prior to my surgery and not after it.
