knee and feet

[Deleted User]

i have had sore knees for a week now, having only started running a week before that. i am out of shape, but have been surprised about not being out of breath, just struggling physically. i do walk a lot, so the injury has suprirsed me even more. both knees are extremely painful on the inside just below the kneecap. my doctor has said it is the muscle and has given some exercises to do.

 

both feet hurt, the soles feel very heavy and hot, and htis is just from walking, never happened before. in particular the outside edge of my right foot is very sore and painful, pretty much halfway between my toes and heel. any ideas what it coudl be? i wear running shoes that i bought from sweatshop having been filmed on a treadmill so am confident my shoes are good for the job
