Living with Anxiety Symptoms. Me?

I've been diagnosed with anxiety attack/panic attack 3 weeks ago and have been experiencing anxiety symptoms since then. 1st week I had chest pains, palpitations and hot flashes that occurs almost every 15 mins and lasts for a few minutes each episode. I also had upper back pain, shoulder and neck pain. I also had a difficulty swallowing, tiredness and headache that feels like pressure. ECG and thyroid tests came back normal. The doctor gave me meds for acid reflux, and took it for 8 days. He also gave me Dolo-Neurobion, for pain relief and vitamin B-complex. 2nd week, I had relief in my back and shoulder pain as well as chest pain and practiced deep breathing. I practiced not to be overly aware with my heartbeat. 3rd week, I only experience warm feeling, if it gets warmer, my skin develops red spots, mostly in arms, but not itchy then subsides when I feel cooler; headache, and some dry skin. How long will my body recover from this anxiety symptoms? What can you recommend me? Thank you
