Plase can someone give me there opinion about something thats worrying me quite a bit today.

I have noticed that the last few days my second and third toes - from my big toe are a bit numb and i keep feeling like the blood isnt flowing there properly. I just want to know if I am right to assume that its becuase I have been wearing sandals that have a bit that wraps around my big toe and puts quit a lot of pressure there. Im hopeing that its putting pressure on the nerve there and that its not that my circulation is poor

sorry, quite scared
