Thanks for writing in.
Your symptoms of sweating, headache and dry throat might be due to the side effects of oxycodone
. Stop taking oxycodone.
I would suggest you take an over the counter pain medication like paracetamol
for pain relief.
Apply pain relief gel like diclofenac
gel or volini gel. 15 minutes later apply hot fomentation on the back.
If there is still no relief, I suggest you visit your doctor.
Hope this helps.
