Doctor's Notes on Meningitis in Adults
Meningitis is inflammation of the meninges, the membranes that surround the brain and spinal cord. Meningitis can also be associated with inflammation of the brain tissue itself, known as encephalitis. Meningitis may be caused by infections by a number of different viruses, bacteria, fungi, and parasites. It can also be due to non-infectious conditions. Diseases and conditions that can lead to widespread inflammation of body tissues without infection, such as lupus, may cause aseptic (non-bacterial) meningitis. Certain medications may also cause non-infectious or aseptic meningitis.
The characteristic symptoms and signs of meningitis include headache, fever, and a stiff neck. There is usually a painful sensitivity to light, known as photophobia. Associated symptoms and signs can include

Pain MedicationsThe effects of pain medication are different for each person. Pain also varies in tolerance as well from person to person. There are several different pain medications such as NSAIDS, acetaminophen, and narcotics. The most commonly prescribed narcotics are morphine (MS Contin, Avinza, Kadain, Oramorph), oxycodone (OxyContin, Roxicodone, M-oxy, ETH-Oxydose, Oxyfast, OxylR), fentanyl (Duragesic, Fentanyl Patch), oxymorphone (Opana), and methadone (Methadose) Narcotic pain medications can lead to physical addiction. Symptoms of physical addiction to narcotics include flu-like symptoms, nausea, vomiting, diarrhea, bone aches, feeling like you are "crawling out of your skin," goose bumps, chills, tremor, and difficulty sleeping. These symptoms are all medical concerns and should be treated medically.
