Consultation Required. For vomit.

My mother was suffering from high blood pressure and urine infection earlier and continuous vomit day-to-day. One night her B.P. increased drastically and she had short breath, her oxygen level was 66. I admitted her in hospital. She did not have COVID-19. They shifter her in MICU with continuous oxygen. Doctors did some tests and investigations and found that she has liver, kidney and blood infection. She had some water in her lungs too (short breath was due to this). They started their treatment and her condition improves and she discharged from hospital after 15 days however now her b.p. is controlled and urine is fine but no improvement for vomit. She is unable to eat anything as it comes out as a result of vomitting. We consulted with our doctor and they prescribed some medicines but there are not much results. Now the main concern is vomit. I am worried and want to consult with other doctors. I have all tests and reports. Kindly advise me in this regards. Thank you!
