Developed sudden numbness below my left kneecap extending down lower leg (affected area slightly larger than a fist). saw dr and neurological exam showed diffuse brisk 3+ patellar and achilles reflex and absent tricep reflex. related to numbness?

Hard to sensibly tie all this together. The leg numbness, if inner leg, would fit a saphenous neuropathy, a benign sensory problem unrelated to the reflexes. The triceps absence may relate to a C7 neck lesion. The brisk leg reflexes could be due to neck problem or heightened anxiety. Need much more information to make sense of this. See a neurologist and get fully assessed.
