I have gone through your query and understood your concerns. In my opinion the problem you are facing now is associated with irritable bowel syndrome
as it is the most common condition which is associated with fibromyalgia
. I suggest you symptomatic treatment for now. For diarrhea
take cap.zedott and for nausea
tab.ondem. Hydrate yourself well and take electral powder also along with water. Dizzy spells are due to weakness and once weakness is corrected you can be free from those dizzy spells. Thank you.
