Recently for the past few days I've been getting this weird warming sensation in my left butt cheek. Yes I said that! Lol. I'm so serious and it's very weird. It lasts for like a minute, maybe two but it comes on randomly when I'm sitting. It's like I have a heating pad under my butt but I don't. I Googled it and the only thing I found was that it might be my sciatic nerve. But it doesn't hurt. It just feels very warm. I didn't want to Google any further and freak myself and convince myself I have cancer or something lol. Any thoughts?
