I just have a physcial done by my doctor 3 weeks ago. All tests normal.

2 weeks ago I started having bad upper back pain and I felt it was hard to breath, saw my doc and he said it was nothing. Now since friday my lymph nodes are a little swollen and my thropat hurts, not like a sore throat buit like I been yelling.. again I feel shirt of breath.
It almost feels like a respitory infection of some sort but when I saw him last he said he didnt hear anything abnormal in my lungs.

I don't have a fever at all, so it cant be an infection. I thoight if the lymph nodes were swollen you always had a fever. i am embaressed to see my doctor again. I go in june 15 for a blood pressure follow up, but 2 weeks is a long time like this.
