Hello. Thanks for asking from Chat Doctor. I can understand your concern. It is good that after CO poisoning, your consciousness is intact. It means that your brain is almost spared. Your numbness can be due to nerve or spinal cord damage. To find out the cause, the doctor is advising you some investigations like nerve conduction study. Nerve conduction study helps in evaluating nerve damage. In case of nerve damage, conduction velocity decreases. Spinal cord damage can be found out by MRI of spine. At home, you can follow few tips like: Avoid touching excessive hot or cold objects if your extremities are numb, as they can cause damage to your skin.: Wear soft shoes and gloves to protect your skin.  You should eat food which are reach in vitamins and minerals like green vegetables, fruits, curd. It will help in healing of nerves. Thanks. Hope it will help you. Take care.
