I have thyroid cancer ...had Thyroid removed this January has well has right lymph node. Cancer has now spread into right shoulder bone , one of my ribs ,bit at the bottom of the back and a small spot on base of skull.

I have arthritis in both knees.

My question on Sunday I have 3 sessions of hiccups during the day.

Can't remember the last time I ever had them - must of been sometime last year.Haven't had them since the op until Sunday.

Haven't had them since Sunday. By-product of the operation on the thyroid ? Or am i reading too much into it? 

Ever since I was diagnosed every ache and pain is under intense scrutiny by myself.

Any advice gratefully received.
