What could weight gain, fatigue, increased heart rate and sudden swelling of the hands and feet with shortness of breath when laying down indicate in a 27 year old female? what budget friendly test would you suggest?

Virtual consultation: A virtual consultation on Healthtap may be useful to you and your PCP. I would suggest checking your BP, Thyroid Hormone levels, a Chest Radiograph and EKG 12 lead. Reduce excessive salt intake and adhere to a healthy diet. If you are having difficulty breathing, please follow up with urgent care or your PCP. Monitor your temperature and watch for worsening or additional symptoms.

Need eval: I agree with the earlier posting about having this assessed. However, I don't know of any inexpensive tests that you can perform on your own that will help you diagnose your problem.
