I had bacterial meningitis, pneumonia and pleurisy back in March 2013. I was misdiagnosed and given the wrong antibiotics, so my pneumonia and pleurisy were cleared up, but the meningitis raged on. I was in severe pain for over 7 months, unable to walk, or bear daylight, unable to read, watch TV, use a phone or listen to the radio. I had to lie quietly in a dark room day and night for months and months. My neurologist says that I then developed encephalitis which is apparently why the pain is still continuing - I'm now into my 12th month of illness. There is no way that I could consider doing any work (ironically I'm a neuroscientist). I cannot go in a car and can't bear any sun on my head whatsoever.
No medications alleviate the pain (as I know others have also found). I tried High Flow Oxygen, but that only helped for a couple of weeks to slightly alleviate the pain and, after using it for 7 weeks, I've now given that up. However I have found that a 'Cooling Cap' is hugely effective in temporarily alleviating the pain. Here's a link to the company I found which is in Australia (I live in Sydney), iceheatwraps.com.au/coo... . I don't know if they send them abroad (they probably do), but you may find other manufacturers in your own countries. I hope that it might help others too. It doesn't make the pain go away, but it reduces its severity and, more importantly from a neuroscientific perspective, we know that inflammation of the brain is detrimental and may be implicated in many brain disorders, such as dementia. Therefore reducing inflammation is likely to reduce that risk. I for one am doing all I can to minimise the risk of long-term damage following this dreadful meningitis and the cooling cap does seem to help.
