What causes raised lymphocytes and enlarged lymph nodes in toddlers?

To add-my son is 18 months old, and has had enlarged lymph nodes in his neck since birth. They are so large you can see them from across the room. His doc ordered a CBC and initially it came back with a total WBC count of 12.47 and lymphocyte count of 8.48. He said the WBC should have been around 10 and the lymphocyte around 4. Then a month later his WBC was 16.15 and lymphocyte at 8.08. Now a week later, his WBC is back down to 12.5, but his lymphocyte count raised back to 8.78. The only other thing he said was off was his MCH (mean count hemoglobin??) at 25.3 which was a little low. All his other types of cells are normal, including his other WBC types. At first he said he was concerned with his number of lymphocytes being so high, and now he is saying it might just be an infection that is getting better. Is it normal for your WBC to go down but your lymphocyte number to increase? Everywhere I read about it your lymphocyte number should be within 20-40% of your total WBC count.

How will not taking antibiotics properly affect your immune system?

Not taking your antibiotics properly is really very detrimental not only to your immune system but also to your general health and others too.

If you know what MRSA are you might have a greater understanding and perspective of this. Most MRSA are cause by the improper use of antibiotics where the infection wasn't properly destroyed and eliminated from the body so it eventually mutated and became resistant to the antibiotic treatment. However my advise is once you have completed a round of antibiotic treatment go on another round of herbal antibiotics such as Oregano oil, Aloe Vera or Garlic (the type chosen is dependent on the infection you need treated. Oregano is a broad spectrum natural antibiotic). During and after which you drink a lot of fluids to flush your system and then follow up with a few nutritional supplements such as Bee pollen.

What can cause elevated lymphocytes?

An elevated lymphocytes level means that you have a higher than usual amount of white blood cells called lymphocytes. Because these cells are used to fight of infection, people tend to produce more of them when they are ill.
