That sounds an awful lot like gout, which I thought I had recently, as my big toe was hurting bad. I researched gout on the 'net after a coworker said it sounded like her dad's gout. Gout is caused by too much uric acid in your body, & not being eliminated normally. Drink a lot of water if you can manage that, & see if it doesn't help. See your doctor & mention gout & see if he can test to rule it out. There are a few tried-and-true medications for gout that he can prescribe. Best of luck! By the way, after I switched jobs & got off my feet, my problems have all but disappeared. Again, I hope you find the answer!
