Thanks Jen, not sure what type? will have to ask my mum, I went to a party about a month ago and danced all night...for a few days after that my knees were really sore! My mum said that thats how her sisters started. They dont hurt majorly but I can feel a strain on them
Maybe just a bit of a strain then, were you wearing high heels as well?
Won't hurt the doc to take a look and keep an eye esp if certain types of arthritis are in the family. They may be able to suggest exercises and supplements and such to keep them healthy.
