Karina -
Congratulations on getting through the surgery. (First couple of weeks are the hardest.)
I would ask your pharmacist about which pills can be crushed. Once you determine what can and cannot be crushed or substituted with liquid versions, I would recommend soaking the crushable medicine for 10 to 15 minutes before attempting to swallow.
I see an endocrinologist because of long term damage to my thyroid from radiation treatments to my neck, (1997). Not certain as to why you were directed to see them now unless its to establish a baseline of thyroid function. (The best option is to ask the endocrinologist when you visit.)
Christine provided some good information on the sutures and pills as well.
Good Luck
