sometimes it feels like my skin is pulsing but not often, I am probably way off but have you been tested for parkinsons?

no I haven't and I doubt it's that cause it's only one hand

I get that too. I never used to get that symptom but I started to get it from my IV antibiotics as a herxing reaction. It shows that they Lyme has done or is doing some serious neurological damage and can cause something like parkinsons (Lyme can imitate parkinsons and alzhiemers). If you aren't undergoing treatment for Lyme right now you should really start again and detox as much as possible (suanas, hot tubs, and warm baths help with this, there is also some medication for things like metal poisoning or chemical poisoning that is shown to help get rid of the toxins that build up in our bodies from the bacteria).

Shaking has been one of my biggest symptoms from the beginning, and it is worse now because I have been on antibiotics. Almost all my muscles spasm or shake when I change from using one muscle to the next (for example putting my arm out and then bringing it back - different muscles used for each motion so then my arm shakes/spasms). It is bad in my arms/legs. The things that shake 24/7 are my hands and my jaw (whether or not I am using them). Even my tounge spasms and shakes.

I shake worse when I have been doing too much (like taking a shower and getting some breakfast - pretty strenuous huh?). Thus nights are worse from the daily activity. And it is strange that it is really bad when I just wake up, and I'm still in bed.

Sometimes it freaks me out and I worry that something else is wrong with me, but usually I trust what I have been told... that it will get better when I've been on antibiotics longer.

You might want to try some detox, it might help with the symptoms. I also found out that phenergen and zofran help (I think it is the phenergen but I take them together so I won't ever know) calm the shaking greatly but also make me really exhausted and tired so I can only take them at night.

My hubby also shakes, has done so since he was a teenager, but we think he got Lyme as a kid. His hands shake a lot. He also gets a lot of muscle spasms now since starting abx. He has restless leg syndrome like nobody's business!! His legs are always moving!

I do this, sometimes. I up the vitamin B's.

I do. I get tremors, not really noticable to other people. But then there is the real shaking, which is. Driving, my right leg spasms like mad, also when shaving my legs, when I bend down to pick something up, my whole body shakes. When I am shaking or having tremors, my muscles feel extra weak.

Also, standing too long makes me shake. Anything where my muscles are doing the littlest bit of work, they shake. Very weird. And scary.
