I went to the ER they gave me cephalexin 500mg

Thanks for your concern

I'm taking cephalexin for HS. You just can't take this antibiotic with methotrexate together, if you're taking this medication.

Thanks

Praying that you find an answer soon and get it under control. It could be anything so I’d definitely consult with a doctor ASAP!

Folliculitis is a common skin condition that happens when hair follicles become inflamed. It's often caused by an infection with bacteria. At first it may look like small pimples around the tiny pockets from where each hair grows (hair follicles). The condition can be itchy, sore
