Two months back I had the upper lip swollen with apparently no cause; there was slite itching before the swelling started; there was no pain; the swelling lasted for a day. After a few days, there was a similar case of swelling which also lasted for a day; then about a month later, the lower lip got swollen; and then the foreskin of the penis got swollen, which also lasted for a day; now I have the right cheek swollen. I am 76 years old, and my health is quite o.k. I have no blood-suger problem, or blood-pressure problem
