I'm a 23 year old male, last month I had gotten epididymitis, I went to the Dr. and he gave me doxycycline hyclate, by the time I had gotten the medicine the symptoms left and the gland at my waistline went down so I didn't take the antibiotics, now it's been 2 or 3 weeks later and my lower back has been hurting and the pain radiates to my groin, I was feeling in my lower back and it feels like the gland in my lower right back is swollen. What are the possible conditions for that and would the doxycycline hyclate help get rid of it? I still have the antibiotics and wondered if it would relieve me of it.
