This past two weeks it happened to me twice, the first time my feet and hands were numb I felt nauseous and suddenly I had difficulty breathing and felt dizzy I thought maybe it was because of the heat outside but it lasted for two days my dizziness went away it would come back again and again within two days I didn't work for three days and rested but I thought I was okay but when I started working again I felt numb in my feet and hands I was scared so I sat down immediately and that's when it started I couldn't breathe my heart rate was fast my hands were hard to talk I couldn't close them or move them it was like they didn't have the strength to hold anything so I took them to the clinic and there. They just did a terrible job and sent me home I didn't go to work for a week to rest but it's still the same when I work I feel like my hands and feet are shaking my heart is beating fast I catch my breath only when I'm at work I feel like that but when I'm at home I'm okay
