I've got hypermobility which causes me the odd problem, but nothing terrible. However, lately, I've been injuring myself really easily just doing normal day to day stuff. Last week I went out on my bike and hurt my left arm and yesterday I cleaned the fish out and my arm is very painful again 
I'm also very tired and feel all rickety and knackered. I haven't been overdoing it at all and I'm not anaemic or hypothyroid.
I have chronic sinusitis and a headache and I can't see properly - I think it might be eyestrain, but my lenses aren't that old.
I could sleep constantly and I'm hardly able to manage to do very much at all 
I seem to be more wakeful in the evenings, rather than during the day.
Does this sound like anything familiar, or am I just getting old (I'm 42)
