What Causes Swelling In The Lower Legs While Suffering From Gall Stones?

I for a fact have gallstones for a year or more. Its reallllly been bothering me really bad I ve had vomiting, fever, worse pain ever and I ve notice that my feet ankles and lower legs are swollen as well my urine is dark and its not normally dark. Should I go to the hospital asap or wait to see the doctor it will be 3 months or more to get into the Dr. Would you suggest the hospital or my doctor? I am in so much pain and discomfort that I cannot tell you the last time I have slept for more than an hour at a time if that. Also even if I take a drink of water it comes right back up. The Dr gave me Phenergan about 8 months ago for the vomiting back then which I still had four or five left which have taken the past couple of days and as long as I m taking Phenergan I can eat and drink but if I don t take it which I m out now I ll go right back to vomiting and I m getting worried. My mother is a certified licensed nurse but I m even scared to say something to her because I know she ll make me go to the hospital immediately but you know how moms can be so I don t know if it s her making me go because she s concerned or she s concerned because he s my mom or because she s concerned cuz of just flat-out being a nurse. I need help please. Thank you. Jennifer Rowe.
