<s>[INST] I get large lumps on my spine, back of my head, neck which come and go every month.  Sore to touch.  I suffer with hirsutism and have been seen by an endocrinologist who says my androgens are "in normal levels" the lumps last about a week every month. [/INST] Hi.Thanks for your query and an elucidate history. This looks to be due to furunculosis,/ boils. This is due to failure of the skin to adopt to the hormonal changes as you have rightly noticed. Yet you can try this :::Apply liquid povidone iodine twice daily to the area where you get this problem.Take Vitamin A 3 lac units and Vitamin D - 1 sachet daily for 3 days. Also take Doxycyclin daily for weeks - till you get a result. I hope this helps you. No stress is very important... Stress is a cause of many problems. </s>
