Anxiety Symptoms. Still cause this?

Hi, i've been diagnosed with anxiety just 2 weeks from now. I had experienced palpitations, chest pain and hot flashes as first symptoms. Then had upper back pain, neck pain, tingling in the neck or jaw, some headache, fatigue and difficulty swallowing. I've done tests for my thyroid, as per the doctor's advice and everything turned out to be normal. Both doctors that I had told me I am normal and that the symptoms I am experiencing is anxiety. Both doctors are in Internal Medicine and one of whom is an Endocrinologist. Now, the symptoms that I only experience are headache (that feels pressure in the head, mostly at the back of my head, but sometimes above my eyebrows) and warm feeling, mostly in nape area, head (or back of head), armpits, neck and cheeks. it happens most often in the afternoon but rarely at night/morning. When I feel really warm, like when I start to worry, my skin appears to have a rash but never itchy then subsides right away. Can anxiety still cause this? Thank you
