See a neurologist: If your symptoms are getting worse and you have a shunt, you may need to have the shunt/settings evaluated by your neurosurgeon. If no shunt, then see a neurologist. If acute worsening of symptoms, don't delay -- go to urgent care or the ER. If you are obese or overweight, losing weight will help too. http://www.nlm.nih.gov/medlineplus/ency/article/000351.htm
