@gavyn Hello, you may have a disease or condition that restricts blood flow to the hands. Blood flows from the heart to the hands through the ulnar artery and the radial artery. Exposure to cold temperatures causes the muscles around these arteries to tighten or constrict. You may have Raynaud's disease, rheumatoid arthritis, pulmonary hypertension, or carpel tunnel syndrome. Carpel tunnel syndrome condition involves the median nerve becoming irritated or compressed in the carpal tunnel, which is a bundle of tendons and ligaments running through the wrist and into the hand. You have serious symptoms like pain, tingling, numbness, and/or weakness. Please visit a doctor. Thanks.
