I've been using my IFwave unit 3 times a day for the last couple days,, like the stim unit but runs off a lithium type battery and will run a more complex pattern of stim on four leads. I got it perm from the jeep wreck.. used the stim too much at PT so they got me one for home.. Im moving around a good amount better.. every now and then a misstep will remind me whats going on.. I weened myself off all the drugs except the 800 ibuprofen and I'm running out on a service call for work this morning.. see how that goes.. cant wait till I see the Dr on monday to hear about the MRI... I'm just hoping for good news.. I've been trying to figure out which PT place to go to with my odd work schedule.. leave 5:30am get home some nights at 7-8pm.. should be easy....love the busy season...
