,Initial part of Large intestine are present.
The sounds are most probably the intestinal sounds,which are heard during movement,i.e.Peristalisis.
It is a normal phenomenon.
But,if you are having pain in that area,you have to go for an Ultrasound
abdomen with the advice of your doctor.It will give a clue whether the pain is due to Appendicitis
or Right side Ureteric stone.
Regarding twitchings in the chest,eyelid and neck are of least concern unless they are continuous and associated with pain.Then you have to Consult your Physician and get examined.
