I have 2 very small, like pea-sized, hard lumps between my neck and shoulders just to the right of the top knob of the spinal cord.  They hurt to the touch, very tender.  I also have an extraordinarily stiff neck when I try to turn my head to the right.  I did take a 16 hr plane ride last week, and that is exactly when I found them.  I also am fighting a cold, and just started malaria pills (doxycycline) recently.  Otherwsie healthy. Thoughts?
Hi.it is best if you consult with a doctor, preferably a general surgeon, for medical and physical examination. Two things to consider primarily based from your description
