Hello I am confused about my next action , I have been having these issues for years but just in the last six months have they spiraled out of control. I am a 27 year old female. For the past at least six plus years I have suffered with the following issues. Constantly cold no matter what the temp fatigued for no reason chronic aches and pains , most recently extreme weight gain. I have not changed my diet I eat healthy only drink water juice or tea. Recently memory loss. I was told perhaps thyroid was issues so I went to Dr. They ran blood and felt my thyroid. The blood came back normal except instances that possibily mean I'm border line lupus. But he psyical examine revealed my thyroid to be enlarged. The doctor wrote me off as vitamin d deficient and gave me strong vitamins that have done nothing for my energy or feeling cold. When I spoke of weight gain I'm talking thirty lbs in about a month no I am not pregnant. Once the weight gain began I have been working out since and have not lost a single lbs or inch in six months. I'm still very concerned considering my normal weight is about 115/120 and now I am 145 and holding strong. I dont think my Dr diagnosed me correctly does anyone else have experience with thyroid issues and where I can seek help
