I am 35 years old and almost 20 weeks pregnant. I have always had some muscle twitches here and there. Sometimes they would linger for a few days and other times I just notice the occasional twitch. I should point out that this is a high risk pregnancy due to a septal defect. In the last couple of months, since I have been pregnant, my twitches have increased significantly. It all seemed to start in my right foot after I would stretch my calf muscle in the morning while still in bed. (I have been asked to sleep on either side at night and not my back, so I am not moving around much). It would last just a few seconds and I couldn't reproduce this with a subsequent stretch. Once or twice a day I would feel the muscle twitch in my foot, such as when I crossed my leg or changed positions. One afternoon the I started noticing the twitching more frequently. I became extremely anxious regarding the twitching and within two days I started experiencing twitching in my entire body (arms, legs, eye, rib cage, back and hands). They come and go rapidly. One minute I will feel a quick twitch in my arm and a minute later I might feel one in my leg. They are worse at night and seem to be more aggrevated after moving or tensing my muscles. I have never felt more anxious in my life. I have trouble sleeping and am not eating well. I have seen my internist who examined me carefully, testing my strength and reflexes. Everything was normal and I was reassured that I did not have a degenerative disease. My question is can pregnancy bring on increased muscle twitching? Thank you.
