Aching

I have aching legs and arms for about 2 days now. Legs especially and I notice it more when I’m resting and laying down. Has anyone had this? I know it’s not anemia or an iron deficiency cause I just had blood work done two weeks ago along with an ekg. I also just recovered from the flu. Just curious for opinions. If it doesn’t get better soon I’ll book an appointment. PS I have severe anxiety so not sure if that coup play a part in this. TIA
