Hi, I Have A Friend In India Who Has Been

Hi,

I have a friend in India who has been sick for 4 months. He says he went to the hospital, but their medical care is not as advanced as ours, so I thought I would try to help him.
He says his throat hurts when he drinks cold water, he says he used to have a high tempeture for a while..now, it's just every so often. He says his lymph odes hurt in his neck and groin. He says his eyesight is effected as well. He says e local hospital ran blood tests, a biopsy and ct scan...and they didn't find anything. I really appreciate an answer. He's just a kid, and he's smart..he's been sick for 4 months.
Thank you.
