Chest tightness and shortness of breath, sometimes tinnitus.

First of all, you have been to the hospital, you can't fully see the patient number and information here, only for your reference:

1 Hypertension and anemia can all cause symptoms such as palpitation, shortness of breath, chest tightness and tinnitus, while cervical spondylosis can cause headache, dizziness and tinnitus.

2 examination and analysis: ordinary electrocardiogram? It can only represent a moment, and there are doubts in my heart; Normal blood routine excludes common blood diseases such as anemia; T3T4 ruled out hyperthyroidism normally;

3 should improve the examination: blood lipid, blood sugar, chest fluoroscopy (now many places are social security free outpatient programs) otolaryngologists check the external auditory canal.

You need to improve the above actions before you continue to work hard. Patience is not a very serious symptom.
