I understand your concerns. However, I do feel that you may be feeling a little more paranoid about the entire situation as you have undergone various treatments in the past few years.
Please get your thyroid
profile done to make sure that it is normal and also an ECG.
How to recover from this condition? - Think positive. You have undergone only 2 minor surgeries. Nothing serious in it.
- Forget about the accident that you had in 2009
- Move ahead in life
Regular exercise will help you recover quicker. Eat healthy and sleep adequately.
You are young to have any major health issues now.
Wish you good health.
