What doctor can i go to for limping i been limping for 5 months a neurologist deal with gait abnormality right?

I would suggest either a neurologist or an orthopaedic surgeon. There are MANY reasons for limping and you will require a complete evaluation and testing based on the findings of the physical examination.

Your doc if you are established with a family doc, would be best to examine first. Based on findings and possible leads a referral will be made.
