Hi, This question is related to some problems my mother has, recently it has come to our knowledge that she has a lump behind her knee joint (left leg). She used to have joint pains for a long time now and also she has some thyroid issues and is also taking medicines. She also suffers from gastric as a result of which she doesn't eat much saying her stomach bloats if she eats a full plate .like she can't eat a banana or anything as gastric sets in and recently she is gaining weight but eats just the same as before. Could someone please help me with these issues? She is around 5'5 and weighs around 49-50 kg.
