I’ve had my fair share. I have COPD, so about 3,5 yrs ago my GP who considers himself a pulmonologist declared I had lung cancer. An X-ray showed a nodule, which he claimed was lung cancer and wanted to do a biopsy, immediately. I told him I was seeking a 2nd opinion. BTW had just had pneumonia. Anyway, off I went to the 2nd opinion, actually a pulmonologist (we’re talking private hospitals here). New doc did another CT scan and told me to wait 6 months. After 6 (worrying) months, a PET/CT scan was performed and the nodule was almost gone, so no lung cancer. However, a couple of months later I develop a heart flutter, due to anxiety of lung cancer. I was in ER and given Cordarone, a heart drug to regulate the heart beat. After a day or so, I realised this drug caused insomnia, so I was given zolpidem. In 2 weeks, I was so dizzy I could hardly stay upright. I had begged the cardiologist to stop the Cordarone pills, but was told I might die if I quit. After 2 months, I was admitted to ER again, I was so dizzy and nauseous, they suspected a stroke. Stayed overnight, an MRI confirmed no stroke and was sent home. After blood tests it was confirmed that my TSH had risen alarmingly (one of the many known side effects of the heart drug), so cardiologist finally said I should quit. Now, however, this heart drug has a half-life of up to 140 days! So side effects continued. Next problem was to quit the zolpidem sleeping pills, aaahhh this was hell. Rebound insomnia is not very pleasant. Took me 6 months of weening off that. 2 yrs later still suffered from sleep latency, could take 3 hrs to fall asleep. So 2,5 yrs of my life was destroyed due to a wrong diagnose and iatrogenic problems and drugs. If the cardiologist had listened to me in the first place, he would have waited a while before prescribing such strong a heart drug. Needless to say, I have left the allopathic system with the exception of emergencies, accidents, acute life threatening situations. I have found a functional doctor now and have been under TCM treatments and have never felt better in my 77 yr old life! Hospitals, these days are business models, excellent for surgeries and life saving acute ailments, but hopeless with chronic or metabolic ailments. Our bodies are not made up of spare parts but of systems with communication pathways, all have to be in harmony for each and every part to work properly. Sadly our modern allopathic medical system does not honour that.
