Hi, I HV these swelling coming and going around the eyes, lips , throatedema, and sometimes around the arms and legs. First there is itching and then the swelling develops, these swelling doesn't have irritation. I m facing this for past 5 months, this is traumatic . Every morning you wake up check if there is any kind of swelling. I got my blood test done, liver function test, kidney function test, all are normal. Kindly advise if there's is any further test to ascertain the cause. Will be helpful. Thanks in advance.
