Yes, another medical thread. Well last night while doing my homework around 10:00 I noticed my left forearm felt funny but shrugged it off because I was working hard. I dropped my pen and reached down to grab it with my left hand and an intense yet non painful pins and needles feeling exploded from my lower forearm/wrist area. Then I noticed that for a while that my arm had been very numb feeling. Basically between my elbow and wrist area I have very reduced sensation- comparable to how numb your skin is after using ice to stop swelling, if not a little worse. My arm is not swollen and seems symmetrical with my other arm. So basically all day my forearm has been numb with the exception of the underside of my arm in line with my pinky finger. My sensation in my hand is probably about 90% and movement wise about 85% (can't move fingers as fast or with quite as much control as normal it seems). I've also had random areas of pain on my arm similar to getting hit with a lacrosse stick or some other blunt object. Does this sound like a pinched nerve? I am guessing its the Ulnar nerve after quickly looking in my anatomy book haha. I supposed it would be pinched in my elbow, shoulder, or back. Bad backs run in my family and I have back pain believed to be caused by neuromuscular dysfunction (using wrong muscles for certain tasks, actually a fairly normal phenomenon). If this is a pinched nerve how long does this last and is it vital to seek medical attention? BTW I am 17 and active.
