Hands feet are always freezing! when i take a lukewarm shower my feet feel like they are on fire. left side is always colder than right side?

Cold feet: Your issues could represent something called Raynaud's phenomena or vascular diseasebbz. Generally with cold feet, signifies a vascular issue but could also be neurological. There are several tests that can check the vascular system as well as a neurological system and you can always get an MRI. I would see the closest neurologist, vascular specialist and/or podiatrist as soon as you can.
