Thank you for the question. Rightfully as Dr Dinesh has mentioned, the numbness and/or colour change can be due to various causes, and commonly could be due either to a nervous (central or peripheral nerves) problem or even a vascular (bloodflow) problem.
It is important to identify the cause, and get that checked up, as these symptoms may be persistent, or even start affecting other toes/ part of the foot.
I think you should see the camp MO, and get a referral to see either a vascular surgeon, or an orthopaedic surgeon. They can then do the necessary investigations, to try and identify the cause of your symptoms, and start the proper management for you.
Best regards
Dr Sean Ng
