I was recently diagnosed with HPV, that I received from my fiance of whom I have been with exclusively for almost 3 years. My doctor prescribed me a low-dose Naltrexone in an attempt to help me fight off the virus. After taking it for 2 weeks (Sept 17th) I started to swell up, it started at my neck and eventually spreading everywhere. After a week I started to feel back to normal but then a few days after I felt back to normal (the 27th) my neck & cheeks still feel swollen. I wake up with pain in my jaw and it's somewhat painful to eat, although bearable. I went to the ER the first day when it was just my neck because I had to work all weekend and was worried I wouldn't get a chance to go to the doctor if it got worse. He said my lymph-nodes did not look swollen and that it could be a number of things including allergies or pharyngitis as a side affect of the Naltrexone. Any clues as to what this may really be after all and why it's still lingering? I feel like I should mention that I do have anxiety but I do my best to stay calm about things but I can lose control and let my emotions take over my body.
