Hi doctors I wonder if you could help me, for a long time now I have been having acheing legs, but they don't acheing as much they just feel tierd. I am a joiner and I stand for at least 10 hours a day so I am wondering if it is that. During work , my legs feel hot and they ache at the same time . when I feel I can't stand on them anymore, I will go into the toilet and put cold water on them and they feel lots better. I also worry about the way I stand too, my knees go past straight they bend further back when I stand. My knees do point out a bit on the right side of both knees . I also can't do squats or bend down as my legs hurt and shake. During the night, my legs will ache and feel uncomfortable, causing me to stop sleeping. The only way they feel better is by putting them on something ( my poor partner most of the time) so they are bent and high up. My partner was feeling my leg and they found a spot where it hurt the most which is in my knee cap. I have recently had a back injurie in the lower back could this be somthing to do with it ?? Also I get headaches lots too.
