hello, my daughter has a lump on the back of one of her legs on her calf. she says it doesn t hurt when she walks but if she touches or rubs it, it hurts terribly. i ve already seen our doctor and he says it must be some kind of infection that her body is fighting off. he gave her some antibiotics to take but she cannot take any antibiotics anymore because she has taken so much over the past few years. she gets so sick to her stomach and throws up. so, what do you think this is or is coming from? could it be a cist that should be removed? should she have an ultra sound? my daughter s immune system is very low. my husband and i adopted her from india when she was 3 years old and she was severely malnurished at the time. her health seems to be going down hill as she gets older. she is now 17. we have her on a good many vitamins already. our doctor suggested that she have a vitamin profile blood testing done to see if she is lacking certain vitamins or minerals. maybe she is taking the wrong vitamins for her body. please help! thanks, bonnie albury
