I keep getting twitches by my left rib cage and in my leg stomach and sometimes my back i have health anxiety and it's scaring me. it's not everyday ?

Random twitches : that do not follow any known anatomical pathway or sequence are highly unlikely to be from a disorder of the central nervous system, peripheral nervous system, neuromuscular junction or muscle fibers. What can hurt you - & your fetus, should you become pregnant - is chronic anxiety. Ask your GP for referral to a psychiatrist & a psychologist for proper evaluation, therapy & possible medications.
