Going to see my OBGYN tomorrow.
Hi
Welcome to the MedHelp forum!
Yes, implanon could be the cause for vasodilatation. However, it could also be due to anemia causing retention of water. It can be due kidney or liver disease, electrolyte imbalance, polycystic ovary, low protein in the blood, and disorders of adrenal gland. This is something for which you must consult a doctor ASAP, preferably an internal medicine specialist.
Hope this helps. Take care!
