so sorry to hear that your symptoms are getting worse. You say you have been on plaquenil for 3 months...it often takes up to 6 months for plaquenil to work the best that it is going to work. After 6 months on plaquenil with no real relief, my dr. started me on methotrexate. Yes, it has really helped me especially with fatigue. However, you need to really investigate whether or not you want to go this route. It lowers your immune system, leaving you susceptable to other problems. Also, the day after my dose (via injection), i feel really bad and stay in bed all day. I am very pleased with the present relief from mtx, but i am definitely concerned about what i might be subjecting myself to in the future.
Why don't you call you dr. and see if there is anything they can do for you that will get you out of this flare that you are in.....they might be able to help you.
