Recurrent Hydradenitis Suppurativa

Patient: I have recurrent hydradenitis suppurativa. I have been taking Doxycycle Hyc (as it appears on my prescription bottle) 100 mg. Not only do the abcesses come back, but since I have ben taking the medication, there are now several small modules growing under my armpit. the medication keeps them tiny, but the infection is still there, and now i have a cluster durectly under the skin. it is difficult to move my arm. what should i do next??
