Medical leave

How do I get my doctor to listen to me.. I have been telling them so much stuff and I honestly feel like they don't care.. I have extreme acid reflux it doesn't go away.. i was taking way over the limitof tums a day.. at least 10 to nomore a day .. allwas told was to try pedcid so I did yeah it helped a little but I'm still taking like 6 or more tums on top of the one a day pedcid.. I wake up with acid in my throat which makes me cough.. after work everyday now I go home and throw up acid..

Also my feet and ankles and legs are so swollen I can't bend my toes and it hurts to bend my ankles to walk.. I want to go on medical leave because at my job I'm not allowed any breaks and whenever I try to sit down for like 5 minutes my stupid boss is like I need you to go do this and that .. Everytime.. so about 3 hours into work my feet hurt so bad I'm ready to cry.. my feet are so red and swollen and I also have leg pain so it hurts when I walk.. the pain starts at the top of my leg and wraps all the way around to my back and stops it hurts whenever I do anything with my leg..

But the point is my doctor doesn't care that I'm in so much pain.. I'm tired of forcing myself to go to work and work through all the pain.. I want medical leave.. I only have one month left before the baby so it's not like I'm asking for a whole bunch of time off .. 😭

Update: medical leave not maternity leave.. I don't want to take my maternity because I only get 6 weeks and don't want to go back to work right after the baby is born.. so I want medical leave and then when baby is born maternity leave
