<human>: I am a 28yo F and woke up with red lumps on my shin roughly 3 weeks ago. One below my left knee cap and 2 on the right near ankle. At first I thought they were welts from a bug bite but they dont itch. They appear red, tender, inflammed, painful when walking and feels hot. Only ice seem relieve the hot feeling. I was given Keflex 500mg QID for 10 days and applied triamcinolone prn. Its been 2 weeks since I completed the antiobiotics, the right side seemed to heal on its own, which now appears bruise-like brown color. The right side recently got inflammed again and now my ankle and foot is swollen. I ve been taking aleve to help stop the inflammation but no results. Researching online I ran across Erythemas Nodosum. Is it possible that I may have this? I am on Tri-nessa for 10 yrs, however, my red inflammation is about 4-5 inch in diameter on my ankle.
<bot>: Hello. You give the classical description of an erythema nodosum. According to the history it is erythema nodosum. But confirmation of the diagnosis done by histology. There are a lot of causes for that skin condition. In your case I think long term usage of hormonal contraceptives. e. opossum can disappear on their ownleagij if recurrent eruption occurs I usually give an oral steroid. When we see erythema nodosum, we have to find the under Lin cause.
