Hi There I Am A 28 Year Old Female. For

hi there I am a 28 year old female.
For the past two weeks I have been feeling very run down, very nauseous, and having hot cold sweats
I am on vicoprophren 7.5 ml with 200 ml of ibuprofen I take for my back and have been on it for 2 years (which I know I will coming off it because of the new laws but am not concerned about that or about having withdrawals bc I can go a couple days without it)
Last Sunday I woke up and was vomiting every 20 minutes from 8 am until about 4pm and I mean hurling from the bottom of my stomache and didn't go into the er bc I was able to keep down a banana than around 9pm until 3am I had a severe case of restless leg syndrome(I have only had this once before about 10 years ago
I will tell you I started a new job that is extremely overwhelming and very demanding and have been working a lot of hours which would describe me feeling run down... But what about the nausea and hot cold flashes?
I'm nervous bc my girlfriend was feeling the same way 3 years ago and it ended up being leukemia
Any thoughts? Would stress cause the nausea and hot cold flashes? I also drink a couple glasses of wine every night... Hope I have enough information in here for you guys to guide me in he right direction
