Hello, I am 42 years old busy mother of 3 young boys. In the last 9 months, I have gained almost 20 lbs! I work out 3-5 times a week, eat a healthy diet and drink plenty of water. I have been having various symptoms for the last few years and nothing can be found. These symptoms include: swelling of left fingers while sleeping with a tingling sensation, a stitch in my left side below my rib cage, occasional spasms in the same left side (almost feels like a Charlie horse), rashes and increased fatigue. I am very frustrated and can't seem to find any answers. I had my thyroid levels checked about 3 months ago but they came back normal. Would this be worth checking again? My mother has Hashimoto's. At this point, I would take any suggestions and or advice....I am to young to feel this bad!
