[|Human|] I am on my second round of Keflex for enlarged lymph nodes under my left armpit and above my left collar bone. They are fairly large and could be related to a possible month old spider bite that has not gone away. It is on my left hand, hard, round, and red. It is small in diameter and only hurts when touched. Thanks
[|AI|]  Hi. Welcome to Chat Doctor . I have gone through your query and can understand your concern. As per your complaint in case if you have a spider bite that has not yet resolved even after one month there is a possibility that there is infection in the area of the bite as well as there is allergic reaction due to the toxic chemical injected by the spider sting. As you are already taking antibiotics I would suggest you to also start taking anti allergic like Levocetrizine or Ben Chat Doctor. . Apply steroid ointment over the bite along with Triple antibiotic ointment. Do warm compresses over it. You should also do warm compresses over the swollen lymph nodes. In case if the lymph nodes does not regress in size then you need to get a Biopsy of the lymph nodes done to rule out the exact cause of Lymphadenopathy and treatment can be planned accordingly. Hope this information helps. Thanks and regards.
