<s>[INST] My legs are restless at night. But during the day working out or doing school work, legs tingle and fall asleep at random. Mainly my left. My hands/arms do occasionally as well & I noticed an enormous purple bruise on my right calf about 5 days to a week ago that I don t recall causing and that hasn t appeared to get much better with daily workouts [/INST] Hello,Thanks for the query,Your restlessness, tingling etc could be due to problem in peripheral nerve which is well-known to cause restlessleg syndrome at night.  This can be resolved by a nerve conduction test and video-polysomnography. Your purple bruise in the right calf needs clinical and lab evaluation with platelet counts etc.Hope this helps </s>
