On the third day of taking it, I started feeling?a minor tingling/sunburn sensation on my outer/upper left arm. Over the next days, the sensation spread to my lower/outer left leg. No pain, just the tingling/sunburn sensation - much more noticeable at night when I was trying to go to sleep. I emailed my Dr and he agreed that I should stop taking it. I stopped after taking 13 of the 21 pills. The concerning/scary thing is the the sensation hasn't gone away, in fact, if anything, it's spread. Interestingly, it pretty much goes away when I'm active, e.g., walking, jogging, etc. Has anyone experienced something similar with Keflex? If so, when did it go away. It's been 10+ days since I stopped taking it and the sensation continues. I experienced NO other side effects.
I was prescribed Keflex (500 mg three times per day) for a UTI.

I had photosensitivity when taking it. Meaning I was sensitive to the sun light. But maybe being active, your body is flushing it out? I'd try a lot of water, yogurt, and maybe try benadryl and see if it helps the skin issue? Maybe it's a slight reaction?
Thank you for your response! Well, it's definitely be sunny this summer in Washington state and I have been outside a lot, so that would make sense. With that said, I'm not showing any visible signs of sunburn or too much sun exposure, but I do have pretty dark skin, so that's not surprising. My biggest concern is that it's not going away. It's not worse, but I would have thought that two weeks after stopping the Keflex, I would have thought the side effects would have gone away. Oh well, I will stay patient :) Thanks again for your response.
