After switching from NVP,AZT&3TC to IND,d4t&ddI I've been having lots of boils all over my body. Is this somewhat related to the new improved immune system or is it a side effect?

Boils are enlarged pustules usually caused by a bacteria called Staph. Boils are not typically associated with HIV and are not a common side effect from the HIV medications. Some individuals who have very low CD4+ T-cell counts may develop worsening of their warts, herpes or rashes particularly folliculitis when the T-cell count increases but I personally have not encountered someone developing boils as their count comes up. So, I am unsure as to why you are having a problem with boils. All the drugs may cause a rash that may cause itching. Sometimes if one scratches and breaks open the skin, an infection may develop but typically this doesn't result in boils.

I would caution you about the use of the combination of DDI (videx) and D4T (zerit). You may be at increased risk of developing neuropathy, pancreatitis and lactic acidosis. You may want to discuss other options with your health care provider.
