Lymphadenopathy / Lymphedenitis

My daughter has been using Rogain since sept 2008. Since a month she has not been well. She developed a lump on the right side, cervical lymphnode. It enlarged and she found it difficult to turn her neck . She could not sleep on that side.The only consolation was that it was painful. Then she was generally notwell. She developed some lumps on the left side also. She had severe nose bloak and crusting in the nose and it bled when she cleaned it. She developed a submandibular gland.
Last week she was in severe pain and was addmitted. She was started on IV antibiotics. Her WBC count was 1000. She had blood tests and the heamatologist ruled out lymphoma. Now they want to do a FNA for her on the lymphnode. She did have some eye problem and now has nose block still. Her lymphnodes are restricted to the neck only and has a small one in one arm pit.
Throughout the weeks before admission she was not having fever but was very tired and was feeling dizzy and felt like black outs. She never had high fever. Then on admission she had fever about 38deg. She has no loss of appetite. She still has a nose block but the bleeding stopped.
Kindly tell me if this could be from the use of Rogain? She has not been using it for over a week now. She uses Rogain 0.2%. Thanks.
