I want my waveform to oscillate from 10uA to 10mA
That's a peak-to-peak value of 9.99 mA or, a peak value of 4.995 mA.
So, use two current sources in parallel; one set to produce a peak current of 4.995 mA and the other set to deliver the offset current 5.005 mA DC.
Current sources in parallel add and you'll get what you require. Example of a 1 kHz sinewave: -
The composite current from the two sources flows into a 1 kΩ resistor and produces a peak of 10 volts and a valley of 10 mV.
