2 months ago, after trips to the US/Poland, I started feeling strange: lower arms tingling, spaced out, hot & like I couldn't use my lungs fully. Over the next few days developed a fever & dry cough. My gp diagnosed me with acute bronchitis and gave me antibiotics (5 days amoxicillin). My chest tightness (front of chest, around heart) was partly relieved, but I didn't feel 100% so went back. The infection had cleared up, but as some symptoms reminded the gp of tb (& I'd been travelling) he arranged a chest x-ray. Showed up clear. Still felt bad, esp. at night: lightheaded & often as though someone pressed the air out of my chest on exhaling. Heartrate was 45; during the 2-sec intervals when it felt as though the air was pressed out, my heart didn't beat at all, as though skipping a beat. Hot flushes but no fever. Saw gp again; the infection was back. More antibiotics (10 days klacid). Again some relief. The 2 wks after the course I felt better every day. Got syrup for the mucus (green on some days, colourless on others). Thought I was cured, but since 5 days ago the spaced out feeling is back several hrs every day. In the evening/night (sitting/lying) I've these feelings of air being pressed out & skipped heartbeats. Heartrate at night is 45, blood pressure 110/60-65. No hot flushes/fever. I wonder if I should request a blood test or some other examination from my gp? Age 32, not overweight, non-smoker, exercise regularly. Father had bypass surgery aged 55. Thanks in advance!
