. I read all thdear doctor, I am 71 years old and began hcg drops after observing two people lose weight with out major proplems. My weight was 204 lbs. I followed the instructions to force eat the first two days gaining to 212 lbs. I have been on the drops and diet for two weeks. i began to have itching and then broke in a painful rash. i did lose the weight I gained on the two day feed and 14 lbs altogether. I take medications that I could not stop for blood pressure and thyroid. I read the research and there was no indication that these symptoms would occur. My doctor says it is an allergy. I did not tell him I was using hcg. Will these drops show up in my blood work?
