Hi, Welcome to Health care magic forum.
As you describe, your symptoms are vague, and not related to one disease.
Your stomach is bloated, and
vomiting has strings of blood. You must be having
peptic ulcer, or
hepatitis.
Poor circulation of the calves, and pitting edema. May be due to the
anemia, or
heart failure.
There is in growth of the nail, it is due to the infection of the toe. The nail is to be removed.
There is change of the mood. Changing every minute.
I advise you to consult a physician for diagnosis and treatment.
Take more of green leafy vegetables, pulses, sprouts, and protein rich foods.
wishing for a quick and complete recovery. Thank you.
