An uncomfortable / slightly tender feeling inside my chest, on the right side of my sternum started around the time that I felt like coming down with a cold, 2 weeks ago. That night when I first felt it I also felt tired, had a headache, heavy head, and a couple of new tender lymph nodes in my neck.
A few days into this cold, I had nausea and vomiting, and one time when I vomited I forced myself pretty badly and I felt it hurting again, more intensely, on the same side inside my chest, then it went away in a few minutes.
Then I didn't really have any other symptoms for a week, my cold also cleared, (I did get some occasional shortness of breath but I also suffer from anxiety) and this morning I slept on my right side in a more unusual position and when I woke up to change my position I felt this uncomfortable tickling feeling on the same right side and felt like coughing when I inspired.
I don't have a cough and I don't normally have any pain when I breathe in and out.
I have made an appointment to see a specialist doctor next week but I'm a bit worried of what it could be. I even thought about lymphoma in the chest, but it wouldn't have hurt/appeared at the same time as the cold symptoms, right?
I'm 28, smoked for 8 years but quit 4 years ago.
Thank you for any help!
