Thanks, BlueIris. I did have another read of it on your advice. Until I feel totally normal again I don't think I will be able to fully stop worrying : ( I have started seeing someone about the anxiety and PTSD now, all of this has kind of made me get around to that finally.
I'm trying to remind myself that there are a few plausible (not terrible) reasons for my recent health issues. And that most people could probably get scared about ALS if they looked up the symptoms. Oh I didn't mention that I've had a neurologist tell me not to worry about it, he wasn't concerned, this was during a visit to A&E in mid December, I was advised to go because of the widespread sensation loss etc. They thought I might have an emergency spinal situation (Cauda Equina Syndrome)
Trying to use other examples too e.g. a few bad headaches doesn't equal a brain tumor in 99.5% of cases. Wow this is so hard. Am very open to advice and words of wisdom from others, if you have the time and emotional energy to help (I know how energy sucking anxiety can be, sometimes it leaves me physically exhausted.) The twitching and aching is pretty bad today, I'm going to go for a walk after lunch.
