My left arm has been feeling slightly colder than the right. It doesn't look blue or pale and there's still a radial pulse but it feels colder when I compare them. I sometimes get a slight tingling feeling too. I suffer very bad anxiety and health anxiety and suffer sensory symptoms with depersonalisation such as tingling on the left side of my face. I have had a MRI and seen a neurologist both confirm the face tingling and depersonalisation is anxiety. So I'm just wondering if the colder arm is something to worry about. I'd like to know it's normal. I have a broken left leg and I'm on levothtroxine for hypothyroidism. I weigh 50kg and am 5 foot 6. I am 26 years old patientold and female. I've had colder arm for a few days now. It is intermittent it can get warm again but usually feels colder.
