About 6 weeks ago one day i was standing for a long time (about 6 hours) i started having tingling sensation in leg after coming back. The tingling reduced but weekness in legs below knee started. Weekness or fatigue was such that i was not able to stand for half an hour or so. Now whenever i wear shoes the tingling starts again. The weekness has reduced. But today i again had to stand up for an hour or so and again tingling has started in feet.. I did nerve conduction study and reports were normal.. Also checked
b12. B12 level is 139 and i am taking b12 tablets.. Can it be only because of b12 or smthing more serious
