In Terrible Pain

Woke up yesterday with slight pain in my right foot big toe.Thought nothing of it & carry on my way to huiting office.When we came back home at night.The pain became more intense to the extend of me unable to sleep the whole night till now.Praying hard that its only a slight sprain & all this pain & swelling is due to me walking nonstop yesterday & it will automatically recover by itself because i'm afraid to go to the doctor as i'm dunno what the doctor will do..scare that it will be very painful.I'm already in terrible pain now so i don't dare to imagine anything more painful than that.Now i'm having problem even walking as i need to limp very very slowly.Tried using icepack to numb the pain but after some time the pain came back again.Its been more than 10 years since i last encounter such pain when i used to sprain my ankle or hand when playing basketball.On a scale of 10 for the pain....i will rate it as 10/10 so you can imagine how painful..terrible & miserable i am now.
