I am 19 year old male and was diagnosed with Epididymitis a couple of weeks ago. Prescribed 100mg Doxycycline HYC TB--taken twice daily for 10 days. Aside from the nausea and headaches, I have recently realized a tingling in my right calf. It has probably been feeling this way for about a week now. It feels numb and while there is no actual pain, it is quite uncomfortable In addition, I recently developed a lump right under my right nipple. It's probably about an inch in diameter and feels as if it's a cyst. Plus, Im not convinced my Epididymitis has totally gone away. There is still some very minor discomfort in that area. Any similar side effects?
