Twitching across Body. If there is any.

Hi Doctor, My name is Deep and I am a Recruitment professional. From the last couple of weeks, I am getting Nerve Twitchings..it started with my nerve on the forehead but now it's gradually happening across body, thighs, feet fingers, even on the head This used to usually happen when I intake salt in the form of Chips, processed food but used to stop after a day. This time it's been continuous for couple of weeks, taking plenty of water to stop and less salt intake but still it's not slowing down. My BPs are usually low or normal 110/70, 120/80 . BPM usually on the lower side, 50-60 during rest. I used to be obese 5 years back and then had high BP, was taking Aten 25 but now in the last 4 years, I have reduced my weight with strict diet and heavy exercise from 98 to 66-68 kgs, height is 5.7, post that BP is normal. Could you suggest me the solution for Nerve Twitching if there is any. Thanks for your time . Cheers, Deep
