In addition, to Ally's assessment and to see a GP....the condition could indicate paresthesia, a problem with functioning of neurons.
Without a proper supply of blood and nutrients, nerve cells can no longer adequately send signals to the brain. Because of this, paresthesia can also be a symptom of "vitamin deficiency and malnutrition, as well as metabolic disorders like diabetes, hypothyroidism, and hypoparathyroidism".
If your tingling sensation is accompanied by "fear, worry, sweating, dizziness or ringing in your ears", it may be caused by a panic attack or an anxiety disorder.
A tinging sensation is more probably caused by your nerves. One reason that the symptoms seem to decrease outside could be because your attention is taken away from the symptoms by what is outdoors. It could be anxiety. You are more prone to notice the symptoms more when you are in your "zone" inside your home. There is more to attract your attention outside. If it continues to be a bother, I would see your doctor and not rely on what they tell you in an Urgent Care clinic. If you have a GP that has seen you several times and has your medical history, that person is more likely to give a better diagnosis. Take care, Ally
