<s>[INST] My left small toe is numb (as if they were too cold) on the outer and under side. It feels normal on the inner side. It is not discolored nor have I injured it lately. My shoes are not constricting. I noticed this yesterday morning, I thought I wait a day to see if it goes away - it has not. Should I be worry about this? [/INST] Dear Patient, Welcome, and thanks for sharing your concern I went through your query, and I feel, you should see if you have back pain, as this numbness could very well be due to disc prolapse, you should see if you have had any past or present episode of back pain. The second common course could be peripheral neuropathy, and that can be there if you have diabetic status since long or are chronic alcoholic. I hope my advice would have been useful, in decision-making regarding your treatment, still if you have any clarifications or doubts feel free to contact back. Thanks </s>
