Subarachnoid Haemorrhage - The Event

What is subarachnoid haemorrhage?

Subarachnoid haemorrhage is a sudden leakage of blood into the space between the membranes covering the brain. It is a serious, life threatening condition which requires urgent medical attention.

Causes

Most subarachnoid haemorrhages are caused by a weakness in an artery called an aneurysm, a swelling at a junction of blood vessels. Although aneurysms are quite common, only a small proportion of these rupture and cause subarachnoid haemorrhage. It is not fully understood why aneurysms develop, but smoking, alcohol and drug abuse and hypertension (high blood pressure) are thought to be risk factors. Another cause of subarachnoid haemorrhage is a bleed from a tangled mass of blood vessels called an arteriovenous malformation. This type of subarachnoid haemorrhage is usually less severe.

Symptoms

The classic symptom of subarachnoid haemorrhage is a headache of sudden onset, usually severe and often described as "the worst of my life". One or more of the following symptoms may be present:

  • • Nausea and vomiting
  • • Decreased level of consciousness or coma
  • • Seizures
  • • Confusion
  • • Photophobia (dislike of light)
  • • Stiff neck

I sat on the settee and felt so awful, wondering how much more pain I could take. I felt as though my head was going to blow and suddenly felt and heard a “whooshing of air” through my head and I shouted out in sheer panic. I lost all feeling down the left hand side of my body and I couldn’t feel my leg or walk. I knew that I was going to be sick and I couldn’t move.

It was the middle of the night and I got up to visit the bathroom and a headache came on from nothing to the worst I've ever had in the space of about 30 seconds. I remember laying on the floor groaning with pain and not being able to move my arms and legs.

I had a headache all the day before and eventually felt a popping sensation in the back of my head and passed out. When I came round, the right hand side of my body was paralysed. When I tried to stand I fell over and then when I did manage to get up this almighty pain in the back of the head occurred. It felt like someone hitting me around the back of the head with a baseball bat.

Diagnosis

In most cases, a CT scan is performed which can detect blood in the subarachnoid space. A lumbar puncture is sometimes performed to detect the presence of blood in the cerebro-spinal fluid (CSF).

March 2012 - I got off of the massage table at the spa and when I stood up, my head began to throb and I felt excruciating pain I have never before felt.  The word headache does not do the pain any justice at all.  I got hot and then began to sweat.  I made it to my car, started home and then felt and heard a POP in the back of my neck that felt like someone suddenly hit me with their fist.  I managed to drive 7 miles home, my husband rushed me to the hospital where I finally passed out.  I was determined to stay awake until I got to the hospital because I was afraid I would not wake up again.
