From the last few days I feel dizziness in lead when I stand up after lying down, I feel slight tightness near shoulder joint and because of this I feel some pain in left side of chest especially when I bend forward, in lying down position I feel very minute numbness in left leg and same left feet has pain in heel area especially in morning. I had fever in April first week for 10 days followed by extreme weakness . Covid report was negative but typhoid was detected in Vidal test. I took first shot of covaxin in mid May. I checked myself to cardiologist and ecg was normal. He has asked me to rest for a month and then he shall do stress echo. I'm overweight, 118kg and 6 feet. Pls guide how should I approach to this problem and what could it be?
