she has just had a viral infection, but i am sure she has complained of this before. it is usually when she is in bed at bedtime that she starts complaining of pain in knee and (mainly) underneath the knee, on her left leg. it does seem to appear and then disappear again. i am very sure she has not injured it in any way. this may be irrelevant but she is often complaining of itchy skin, too (during the day it is mainly to do with a certain type of clothes - wool especially - but sometimes when she gets into bed she starts feeling itchy for no particualr reason) so my imagination begins to draw some very sinister scenarios. :( Any advice would be much appreciated, but I will also take her to a doc. She did have fairly extensive bloodtests done recently (when she had tummy ache caused, as it turned out, by constipation) and everything was fine. that was a few months back though. Thank you.
