| Sounds to me like what your gut is telling you is right. your body does not like the medications.
Do you drink diet soda? take Aspartame (equal)? artificial sweetners can exaserbate joint issues like 1000 x in someone how is sensitive to chemicals. Just a thought.
don't let the docs tell you there is no way the meds could cause your symptoms. If they go away when you stop taking the drugs - I say the proof is in the pudding.
I took Januvia and had kidney, bladder, yeast infections and heart issues for 3 straight months. I finally got in to see the endo and she said - couldn't possibly be that - just coincidence. I walked out and never whent back. I stopped the januvia and ta da - I haven't had an infection since, and my heart has stopped racing to 140.
With a body as sensitive as yours - have you thought about going the natural route? You may have underlying food allergies or vitamin defenciencies (I can't spell today sorry). I was amazed at how much better I did overall when I got my potassium and Vitamin D out of the gutter.
Best wishes, keep dialoging on DF and perhaps something will leap out and be a help for you. This is the most frustrating disease I can think of - there are no constants and there are no 'norms' - just a moving target. |
