momof3boyz, I am glad your son is improving.
How long was he sick before getting diagnosed?
Four weeks of treatment is not long enough even if the infection was caught right away. From what I understand, the antibiotics kill the bacteria only when they are reproducing, which is approximately every four weeks. Four weeks of treatment would not even kill one growth cycle if a person started treatment two weeks into the infection. Usually when IV treatment is stopped, it is follwed with oral antibiotics.
Was he tested for the co-infections? This is extremely important. Many people who have Lyme are co-infected and if he is, it will affect treatment choice. Many Lyme doctors believe the co-infections need to be treated first before Lyme treatment is effective. Learn as much as possible. The seriousness of tickborne illnesses is gravely misunderstood by many doctors and patients are the ones who pay.
I cannot stress enough how important it is to see a knowledgeable doctor as soon as possible. Many doctors grossly undertreat Lyme which can lead to it becoming chronic. Once the infection becomes chronic, it can be difficult to eradicate. If your son's infection is early and he gets the proper aggressive treatment now, he has a wonderful chance of complete recovery. I highly recommend calling the Lyme pediatrician in CT to ensure he receives the proper treatment and is tested for the co-infections. Knowing what I know now, if this was my son I would contact the Lyme pediatrician as soon as possible.
Please be aware of the Jarisch-Herxheimer reaction (herx). Often, when people with Lyme take antibiotics, their symptoms may become worse or they may get new ones. When the antibiotics are killing the bacteria, toxins are released making the person sicker. It can be very scary but it is a good sign that the antibiotics are working. People experience this reaction differently, but it often occurs approximately every three to four weeks.
Your son is lucky you are his mom! Please let me know how he is doing.
