I am pain in hip joint area and in leg muscle and my stomach always has some acidity problem
I am not having fever and there is no pain in eyes but temprature keeps fluating from 98.2~98.7F can I have dengue

Your symptoms certainly match that affliction, but those symptoms match flu as well. The ultimate symptom of dengue is extremely low blood pressure, so if I were you, I would go to your doctor and find out if this is exactly what you have.

No one can diagnose over the internet, and we do not diagnose here.
