We Had A Pretty Bad Bed Bug Infestation At The

We had a pretty bad bed bug infestation at the end of September. They were worst in my 15 year old's bedroom. We had a company come up and do a heat treatment and powder treatment in all the bedrooms. I found a couple live ones in my bedroom a few days ago and a shedding in my son's room this morning. My son has had very enlarged lymph nodes throughout his entire body that we noticed at the beginning of October. They are finally slowly reducing in size but we went to doctor after doctor to find out what was wrong with him. For the past few weeks he has been severely congested, tired and has a sore throat every morning. He's been tested for strep and doctors have basically ruled out Lymphoma because they believe the lymph nodes are going down. Can all this be due to being bitten by bed bugs? I'm really concerned now because it's been exactly 2 months since our home was treated and we are finding activity.
