So sorry your Mom is going thru this Leticia! It must be so frustrating to watch her doing badly, and to have uncaring doctors.
If you can find a good general practitioner, or someone who on her side, it will help. Maybe that obgyn can help get the blood tests processed? That butterfly rash is a big clue...and she may indeed have lupus. You're right to try and get that blood test done.
Tecfidera is very hard on the stomach, and there might be a more natural, less toxic way to pursue the action of that drug-using a supplement called Protandim, or simply curcumin, milk thistle and green tea extract.https://www.facebook.com/notes/ccsvi-in ... 4812867211
Get her on an anti-inflammatory diet. Cut back on sugar, transfats, processed foods. Make sure she is getting lots of fresh, organic fruits and vegetables. Some supplements to consider are omega 3 oil (fish or flax) and vitamin D. If she is able to move, keep her exercising. Swimming is good, so is indoor stretching or yoga (if it's too hot out).
Hang in there!
