I'm a hypochondriac and I have fear if I have a brain tumor. I have done MRI of the spine, analysis , neurological test. I tremble and I have weak legs , sore back, arms and hips , insomnia and muscle spasms.
Your symptoms are neuromuscular and may be due to many reasons such as: infections, neurological problems, autoimmune problems or being a hypochondriac. With your age is difficult to have a brain tumor. Keep working with your neurologist.
