In 2017, a mediastinal mass was found in my body and I was diagnosed with lymphoma. One year after the treatment, I started having a lot of fatigue and tachycardia like 160 bpm at rest, and my blood pressure was mostly low (70/40 mmHg).
Now, I am taking the tablet Ivabradine 7.5 mg and the tablet Bisoprolol 5 mg twice a day. I still do not feel good and after a couple of weeks, my heart rate has increased again (above 100 bpm). All the blood investigations for the heart are fine.
I got a CT done after taking the treatment for the lymphoma and growth of 10x11 mm was seen in it. However, now I have got another CT done and it says that the growth is 19x11 mm and there is some 'radiotherapy collateral damage'.
I want your opinion on this.
