Talk to Internal Medicine on Left Side Chest Pain

Mujhe 10-12 saal ki age me left side chest me dard aur breathing issue hota tha. Cardiologist ko dikhaya tha, ECG aur Echo ke baad bataya gaya tha ke ek valve theek se pump nahi kar raha, kuch months ilaaj hua, baad me checkup me sab theek aya. File hata di gayi. Oct 2022 me dengue hua, us waqt achanak oxygen low ho gayi, lips aur hands blue ho gaye the. Emergency me oxygen dene ke baad theek hua. Doctor ne kaha dengue me aisa ho jata hai. Platelets normal thay. Tab se left chest me mild pain rehta tha, kabhi kabhi sans lena mushkil lagta, lambi aur tez sans leni parti. Aakhri 6 months se chest pain barh gaya hai, kabhi strong pain hota hai, sans lete waqt dard hota hai, aram se baithe baithe bhi thakawat aur breathlessness hoti hai. Left hand, shoulder aur back bhi heavy feel hote hain. Kya ye problem serious ho sakti hai? Dobara checkup zaroori hai ya ye stress/irregular periods ki wajah se ho sakta hai?
