Should I be worried about tingling sensation on feet and hands!?

Not usually ominous . While these symptoms are not a call for a major concern, they do merit further investigation. You should try to speak with a neurologist and get the complete work-up. Some things to consider include the mode of onset, other associated symptoms, any change/new meds, and family history. Please write down your questions to get the most out of your interaction with the doctor. Merry christmas.
Neuropathy. Numbness, tingling, burning are all symptoms consistent with a nerve. Most likely there is a metabolic etiology to your symptoms since both hands and feet are affected. Consider seeing your local internist and begin with bloodwork. This could be caused by a neck issue but in the absence of neck problems. This is likely excluded.
