Hi welcome to HCMForum. The arthralgia
of dengue fever
lasts a long course.
You can use pain killers pragaboline like supporting drugs etc. dont keep the limbs
idle or over strained. I advise you to consult an orthopedic surgeon for pain relief.
Besides i advise you to follow some diet recomendations as avoid taking potato
other tubers cauliflower coconut egg chicken and sea food till the pains are relieved.
