I dıscovered a swollen lymph node on the rıght sıde of my sons neck two weeks ago. My frıend discoverd another lump in his groine yesterday. He has no symptoms of illness and the lumps are not big. How ever from 7 months he has had a very slow weight gain some months gaining no weight somtimes droping a little he has gained approx 1 and half kilos in 7 months. İn all other aspects he is developing at a normal rate and is a very active happy baby. İ live in central Turkey so advice is difficult to come by. Thankyou
