Ah, US might be worse

Whatever sickness, drew quite a few tubes of blood.  Recommend you not taking any pain killer even when you were really painful, says easier to find what and where is the problem.  When doctors could not find the problem, refer to specialists and specialist did not know what is the problem and send you back.  More blood drawing every month even though the pain is gone and no symptom anymore. Just kept going and going for half a year.
