I need help

Good morning I have a problem with Edenvale General Hospital. I went there for a check up and they gave me pills when they found that my BP is high. Okay I used those pills but my feet and legs started swelling very bad that when I walk it feels like they'll explode and I started having bad headaches. I went back to tell them but they don't want to listen instead they keep forcing me to take them. What can I do now coz they don't want to listen both the nurses and doctors. These pills might end up giving me a sickness I don't have since they are already causing pain on my body. Please help.
