I use to get aching in my joints loads, havn't had it for ages, had a good day yesterday. Last night was a nightmare, sweating and aching all over. Got up at 3am went and sat with Luke for a bit, who is a nightowl. went back to bed, had horrible nightmares and this morning aching in ecery possible muscle. Feel like I've done10 rounds with Mike Tyson. Also weak and shaky. Does anyone know what causes this and what helps. I use to take vitamin B1 and this helped a bit but this is much worse.
