I am new to this section of MedHelp. As of late May 2010, I've been experiencing weakness of arms, legs, shoulder and hands, intermittent numbness and tingling of the same. A new physician (rheumatologist) has repeated the mri...waiting on results. What started out as suspected carpal tunnel has progressed to a giant question mark. Within the last two weeks, I've started experiencing a buzzing/vibration, which started in my left leg and is now felt throughout the lower half of my body. I've gone through two sets of nerve conduction tests, but not gotten any answers. My biggest fear is that whatever this is is just flying below the radar. The rheumatologist pointed out that I have ridges that can be felt below the skin on my arms and legs. She is also suspecting Schwannomas, based on symptoms. Any thoughts you might have on this would be greatly appreciated. Thank you!
