Question: Hi! I was recently treated for my wisdom tooth infection on my left hand side lower jaw through antibiotics during my visit to the frist dentist, which apparently were an overkill and the dentist who gave me my second opinion told me I could get the wisdom teeth out when I get back home to India. Considering that I have never had antibiotics in recent memory till this occasion, I was diagnosed with candidiasis, or oral thrush, and I am recovering well.
However, there was an acne like structure on the left side of my neck, that happened on Tuesday of last week. I didn't bother with it, until yesterday, when there was some slight swelling of my neck right above the collar bone, and now my left hand side of the neck and my upper left chest feel a little stiff. I have already visited the ENT specialist, who told me everything was fine with me, so there could be no possibility of my thyroid getting overworked. I don't know what it is, it maybe the aftereffects of taking the antibiotics; it is not painful at all, just a bit of soreness that radiates away to my upper left chest and my arm.

Thank you! Hmm, my second dentist said that there was no infection as such in my wisdom tooth when he examined it. As per his advice, I stopped taking the antibiotics since they had caused a fungal infection in my mouth. Also, there is no pain, just a sort of stiffness at times, or more generally a kind of soreness. I'd think if it was the infection, I would be in some significant pain or so. As a precursor, the swelling is not visible, I could only know it by caressing that part of the neck. What else could then be the reason?
Also, I was examined for swollen lymph nodes, and they turned out to be normal.
I forgot to tell you about the dosage of antibiotic I had previously; I had never had antibiotics before as long as I remember in the recent past, and the dosage the first dentist gave me was a 500 mg penicillin 4x a day, which was a bit too much for to take.

Thanks a lot Doctor!
As a follow-up, my upper left chest is a bit sore/tight too. The soreness is centered at the region just beneath the collar bone, but as I had said before, it radiates outwards towards to my arm and sometimes towards the center. I checked for cardiac symptoms just to make sure, like shortness of breath, nausea etc, but none were present. I do get heartburn every now and then especially when I do not eat much or drink much for hours on end. I shall get a physician to check out the nature of the swelling asap.

Yes indeed. Since it is Saturday night here, and it is on Monday when my university's health center opens, I shall keep an eye on it. Also, as soon as I played some tennis a while ago, the soreness subsided, albeit a little bit, so I am guessing it is more musculoskeletal in response to the awkward acne on my neck. However, I shall continue to monitor it till Monday. I shall keep you updated on my situation if you may kindly allow.

I asked a physician on the phone, and with the symptoms I exhibited, she said that the acne could have caused swollen lymph nodes in my lower left region of the neck right above the collarbone, and that most likely it is an independent case from my wisdom tooth. My university opens up tomorrow, so I shall get a detailed answer then, but my mind is now a bit at ease. Would you think it possible that acne can cause enlarged lymph nodes?

Thanks! I did my blood test today, and it turned out to be perfectly fine. The thyroid and the lymph nodes were normal, and were doing okay. The fact that my entire left collarbone and chest, including my neck, were sore, were because of a big neck spasm that has made it pretty stiff for me to move my neck around, hence pretty much my entire upper left body seems sore, and at times hurtful. I was advised to reduce physical activity on that side and drink lots of fluids, and take enough vegetables and fruits as I could.
Also, the swelling that happened in my neck was because of shaving around an unidentified acne that caused it to swell and accumulate fluid. It is a superficial outgrowth, and since it also lies along my neck muscles, it too feels sore. I presume all the stress and fatigue caught up with me.
