Hi there...you can get chicken pox only once in your lifetime. It won't reccur again. What kind of a rashes are you getting now? Fluid filled or pus filled or flat red raised lesion or pin point red raised lesions? Any itching associated with it? Most commonly when rash is associated with fever, it will be a viral exanthem. It will look like small red dots. Usually occurs all over body. It will come down as the fever comes down. So kindly consult a general physician(fever) and dermatologist (rashes) for further evaluation.
