I'm 23 years old male , It all started in April of this year , I experienced hot flush followed by rapid rise in heartbeat (palpitations) and then chills in the body. After couple of days evrything was fine and I was back to my normal routine.
In July I was at work and started experiencing severe palpitations , internal shakiness and rapid heartbeat(over 150).
I immediately called 911 and went to ER , they diagnosed it as PSVT my heart beat was 147 bpm, bp 125/85. Doctors did all blood work, chest Xray. they found my tsh low 0.02 and also ft4 levels were messed up and hence they diagnosed it as Hyperthyriodism (Thyrioditis) and prescribed me propranolol 10mg thrice a day.
I even went for a nuclear scan, which also came out abnormal as a result of inflammation of thyriod glands.
My recent blood work report is normal FT4 is within the limits and TSH is 0.08.
I felt better in a week or so and was back on track. just after couple of days (still on 3 propranolols a day ) I started experiencing this severe internal tremors and palpitations again. I feel shaking and trembling internally, as if motor is running inside my body. When I sit cross leg I can see the other feet shaking, It's very weird and scary feeling and I have been experiencing all these from past 2 months now. I've had two episodes where I felt very weak and fatigued in the morning after waking up and during middle of night while urinating.
My doctor doesn't seem very concerned and think it's anxiety but I guess it's much more than that. As I am writing this, I can feel my heart beating inside my body and I always feel bounding pulse on my neck which scares me much much more.
