You may want to see a neurologist. By no means am I affluent with practicing medicine, but I can relate through personal experience. That being said, I had acquired bi lateral carpal tunnel syndrome resulting from a car accident. The carpal tunnel was impinging the enclosed nerves, and my hands and fingers would twitch or spasm for no apparent reason.
Try to think of any injuries you may have had. Also, consider the fact that many athletes acquire injuries and are completely unaware that they are injured. Sometimes after workout pain has no relation to a "good workout", it may be an injury.
Just a thought...
My friend gets a lot of body twitches/spasms at night and sometimes they do wake him up. Have you changed your diet recently? Have you been working out a bit more? or have u been doing stuff to make u a little more fatigued or stressed than usual? All those will affect ur muscle twitches/spasms. I know it might seem silly and small, but something as simple as relaxing ur muscles by taking a hot bath to unwind them might help. U could try it, won't hurt and will feel good regardless. Also maybe u can ask someone to lend u a hand and giv u a mini-massage or rubdown. So focus on seeing any changes in your diet or physical activity, and do something to relax ur muscles before bed. If all of this won't work, try taking Melatonin pills. It is a natural hormone ur body secrets that helps u sleep well, so I've been takin pills and they help me. It's not like sleeping pills, it's more natural so not addictive or intense.
Good luck!
I was actually watching an episode of "The Doctors" and they were talking about body twitches. That for the most part doctors don't know what causes twitching in general. Like it is always caused by this or that, but my mom always told me that is was a Vitamin deficiency, or if it was in your eye, your tired, overworked muscles, or just transient twitch like KatEyes said too. If it's bothersome, I'd visit the doc.
Since this is a fairly new symptom, maybe the twitches will go away on their own. How is your nutrition lately? Some muscle problems can be nutritional. Also, you may want to make sure you're not anemic.
If you continue to have twitches you may want to talk to your doctor about being evaluated for RLS and/or PLMD.
Sorry I couldn't be more help. I have had muscle twitches that were transient and also had the kind that ended up being a sleep disorder. Hopefully yours will be the first.
there are little twitches that everybody gets. like muscle spazams or something. they're normal. it's just something that haappens... I don't know if this is what you were looking for but, i guess it's something. its probabaly not helpful haha but oh well. imade an effort.
