Stabbing Pain? RLP?

MegSowers

The last few days I've had stabbing pains shoot into my left leg joint (not down my leg, just into the corner). It's like someone takes a knife and does one stab and pulls it out, it's super quick, but makes me flinch. It's happened more frequently each day, though only up to about 8 times at most throughout today. I thought I had RLP in the first trimester, and this is not the same pain. So, it's either RLP now, or something different. It's not a muscle... Thoughts???
