Muscle Twitches - Need some serious help.

I'm having a lot of muscle twitches. The muscles which are most commonly effected are:

- Left Calf. This is a type of pulsate where I can feel it move in synergy to my heartbeat but it has a very "strong" feeling to it. This isn't 24/7, but a few times a day.

- Stomach *always* twitches. Specifically my upper abs. If I had to pin-point it, I would say it's in the ridge in the middle of our chest/rib cages. This also is pulsing to my heartbeat. I can only feel it when I start running/exercising and It feels very strong.

- My (right) Bicep muscle rarely twitches, but still a worthy note: It doesn't twitch to my heartbeat, it kinda feels like a clot is being cleared?

- I get slight lower back aches which recently have started.

- My left eye aches a lot. This is actually something I would love an answer on too: My left eye (sometimes right too) will ache for about 30 mins to a few hours. It causes pain down the side of my neck also. This can happen at any time, e.g. when I first wake up or when I'm at my PC.

- My balance is quite off. I shake a lot when I need to balance on something, for example a log: I could try and balance but I would shake.

Any insight on this would be greatly appreciated, my Doctor has seemed to just brush this off. Tweet
