question: Hi I am 25 and I recently have hit a really busy time in my life. I m not sure if I m having anxiety or heart problems but I have shortness of breath, tightness in chest, dizziness when sitting and I cough for no reason every once in a great while. Although I do have insurance I don t want to go in and have a Doc tell me, oh it is just anxiety. Also, a couple of nights ago I felt like I couldn t breathe when I was in bed and it felt like bubbles were blocking my air way trying to breathe. However, once I stood up and then laid back down it went away and I could breathe fine. Recently my right harm has been in pain when every I move it. The when I message the lymph not between my collar bone and arms it helps. Is this all dealing with anxiety or what? Please help, Thank you.
