Being Unwell with severe chest pain

I've been to see my G.P again about my severe chest pain and she recommended that I go to A&E just to be safe with the Addison's disease so unfortunately i have had a very long and stressful night in the hospital. But the Doctors in A&E were very helpful and after blood tests, a chest X-Ray and a physical examination they determined that the cause of my chest pain is actually Intercostal Neuritis or Costochondritis, which is extremely painful and mimics a heart attack, which is treated with anti-inflammatories. Also the doctors have lowered down my HC back to normal. So I've been taking the anti-inflammatories for a day now and i am just hoping that the pain will go away soon :-)
