hi, i have been experiencing mild tightness in my chest in the past week, this comes and goes, especially when I think about it. no other symptoms. when seeping or resting laying down  this disappears, also when i practice yoga. I have been taking Concetra, and this started at the same time, I stoped taking it 5 days ego, this tightness seems to get better but its still there, at times
Thanks for your question on Chat Doctor. Concentra is hormonal contraceptive pill. It can cause mood swings, anxiety, stress etc. So chest tightness in your case is mostly due to Chat Doctor.  So better to stop this
