I'm 95% sure this is just some particularly unpleasant fibromyalgia pain, enhanced by me getting tense about it because it's got worse all evening.
The other 5% of me is slightly worried it's to do with my fainting and lightheadedness and palpitations - I have a cardiology appointment next year, and had a 48 hour ECG monitor over the weekend.
Lying awake trying to do yoga breathing, feeling frustrated with health stuff and quite lonely. I don't want to worry DP as she is in a different country, it wouldn't be fair on her.
Ho hum.
