Chestpain and bodypain and palpitations.

I am suffering from chest pain , back pain, arm pain and shoulderblade pain for last 4 weeks. It all started after I donated my blood and after a week took a ayurvedic medicine for creating diarrhoea to clean stomach. Before that I had stomach burn issues right after having food so I took it and the issue got cleared somewhat. But it forced me to lot to create vomiting. I have only vomited twice in my life time including this. After these events I had acidic issues and felt something stuck in my throat and I had pantoprazole and after I had excessive burping but the stuck thro at feel gone away. I have been having palpitations for a year when ever I get up so I checked a cardio doctor he said I have high BP around 160/100 but later at rest it was 140/90. I took propanol and it showed some response but when I stopped it palpitation comeback. Now I have chest arm shoulderblade pains but I have normal ecg echo please help me with this I fear it as a serious issue like heart attack,angina
