Muscle twitching weird thing help!
Hi. I just started an exercise program two weeks ago after being mostly sedentary for a year. I have been doing 40 minutes of aerobics three mornings a week. The other day, this weird thing started happening: my left bicep periodically begins twitching for no discerbible reason. It keeps it up for 30-90 seconds or so. This has ben happening several times a day. It doesn't hurt; it feels as if one of those things that make bubbles in fishtanks has started up under my skin. Has anyone ever experienced anything like this before? Is it a bad thing? Good thing? Normal sedentary-body-returning-to-movement thing? Any advice would be helpful. Thanks.
