Hi... I have had difficulties taking deep breaths for the past 3 days.  My chest is very tight and on the right side of my chest there is a knot.  Also I keep wanting to yawn but cant. Omplete the yawn.  I dont feel any anxiety or anything so I dont think that is the problem
HelloTightness in chest and difficult breathing need immediate medical attention. You need proper clinical examination and few investigations. Investigations include routine hologram, random blood sugar, liver function test, lipid profile, renal function test, chest X-ray (PA view), ECG,ECHO, TMT,upper GI endoscopy. Further investigations can be done if needed. Treatment depend upon findings. Get well soon. Take Care Chat Doctor.
