I have a small lymph gland swelling either side of my neck and one in my groin, I have had blood tests and an xray to test for lymphoma and they have come back negative. I feel tired and break out in a sweat on occassion.The outer area of the palms of my hands are very red. I have recently had my wisdom teeth out and there was infection there. Could you please tell me what might be wrong? Thank you.
