Suggest Remedy For Numbness In The Left Leg

I am 40 y o female. My left leg has been troublesome recently. I have had numbness in my leg at night when sleeping. I get vibrations in my leg and ankle throughout the day. Back of knee hurts sometimes and when I bend it it feels swollen but does not look swollen. Not sure if it s connected but my left arm has had some tingling/numbness as well. Also I have pressure in my chest and tenderness/burning. 18 months ago had er visit (chest pain, short of breath) which ruled out cardiac event and dx gastritis (which I believe was not right at all). Did not look for thrombosis at time. During the past 18 months my chest pain has increased in frequency and I was told it was gerd. All the arm and leg symptoms have increased in frequency as well. And I am at the point where I cannot deal anymore. Please give me guidance
