Which side affects should I have after a thyroid ablation?

Maybe transient sx. Presumably you recently had radioactive iodine (rai) treatment of graves disease. The rai will begin to destroy your gland. This may release some hormone and give you transient hyper sx. Use b-blocker, maybe methimazole. Sometime mild neck tenderness. This is usually mild, and most people are hypothyroid within 3 months.
