I had a c-section 3 months a go. since then ( never during pregnancy) having slight tingling and numbness in both hands.worst in cold?

Vascular problem: Normally numbness during or following pregnancy is related to water retention and pressure building within the carpal tunnel causing carpal tunnel syndrome. However, sometime a vascular problem know as raynauds disease, which is a vasospasm triggered by cold temperatures can cause blanching of a digit associated with numbness and pain. A good exam and an EMG study will help provide an answer.
