Hello I have been having leg weakness when I get

Hello I have been having leg weakness when I get to the top of my stairs when coming home, along with being dizzy & when I get into my apartment I have to lean over the counter in my kitchen to hold myself up. It can happen other times as well but only when I have stopped walking. Also my big toes in both feet have been having a burning sensation, tingling, numbness & some pain. I had a blocked carotid artery of 99% blocked & had a endarterectomy for that in April of this year. So don't know if I should go to ER or wait & talk to my primary dr. Thank you
