Detailed Answer:
HI

Greetings from Dr.Divakara.P
Thanks for posting your query.

Well most common cause for tremors and muscle spasm is either calcium deficiency or Potassium deficiency . I hope you have been tested for these levels but if not kindly get tested.

Apart from this the other possibilities include diseases affecting muscles or nerves. Among them I would recommend you get tested for Diabetes, Serum Vitamin B12 levels, Lead levels, TSH, CPK and Nerve conduction study of all 4 limbs.

Kindly revert back with reports.

Hope this information was useful to you.
Any clarifications feel free to ask.

Regards.
