I've always had back pain, but the last few days its been pretty bad. Not done anything that i can think of (ie lifted something heavy) but i've also noticed that the outside of my right foot is numb (3 days now) I've read on t'internet that its probably related, but should i go to the docs or will it just go away on its own? I only bother the doctor if i really need to see him. I do need to go for my next pill prescription in the next month so could just do that early, but appointments are usually a weeks wait so if its gone by then i'd rather wait.
