I'm getting a sharp pain in my big toe on my right foot on the bottom right where the knuckle starts when i walk. should i be concerned?

Get an X-ray: Pain in the big toe can be a presenting sign of gout, but more often than not, a musculoskeletal problem exists - you should probably see s good internist or orthopedist, or podiatrist and start with an X-Ray, however, blood work to rule out a metabolic disorder may be needed. See a doctor first, see what they think is the next best step...
