For 2 days i've had a numb feeling in my left arm , left side of head & left leg ( from knee downwards ) the right side of my mouth is tingly too?

See a Dr. ASAP: You may be having/have a mild stroke and you should be assessed by a physician as soon as possible. If it is not a stroke, ask for complete workup to rule out other issues such as ms or other neurologic issues. It could be a confluence of multiple issues coincidentally happening at the same time, but you need to rule out these more serious issues as soon as possible. Hope all is well.
