i have, in the past few weeks, become very tired, nauseous, and have difficulty breathing with a slight wheeze, sore throat and slight cough with sputum. i have also noticed my breasts are tender and there are lumps in my breasts and a large hard swelling in my left armpit. i m a vegetarian who excersizes on a daily basis and drinks lots of water and takes multi-vitamins, b-12 supplament, cod liver oil and vitamin c. last night i woke up with a horrible cramp in my lower right abdomen and today i ve been bloated. last night i weighed 150 lbs and this morning i weighed 140lbs. my doctor has referred me to an oncologist, but should i return to my previous doctor and request a different refferal?
