For couple of months, her face gets swollen from time to time as if she is having some allergic reaction. This is also seen in her hands and legs. We approached different doctors (medicine, skin etc) did all kinds of blood test (to check allergies,
kidney and all other) but found that every thing is normal. The swelling goes away and comes back time to time. Also, it is observed that whenever she eats protein rich food like fish or soybeans it tends to swell more.
Please advice.
