Effects of egg consumption, abstinence from multivitamin and milk consumption and meat consumption on hand pain

For the past 3-4 months, I have stopped all multivitamins. For the past 20 days (during the fasting month) to 1 month, I have been consuming two eggs per day (one at breakfast and another one at dinner). Also, I have consumed mainly wheat based items for past 15 days.

Positive effects:

1. Reduced anxiety and feelings of joy happened after stopping the fasting. This lasted for few days and start to decrease after that.
2. Reduced stuttering and gasping for breath while talking
3. Increased libido, strong erections, enhanced feeling of orgasm.

Negative effects:

1. Unable to sustain focus or concentration on research related work (review and writing of papers).
2. Reduced productivity in terms of research related work.
3. Hand pain, lower back pain and buttock muscles pain (gluteal muscle) slowly start to occur after 3 months of abstinence from multivitamins. Sometimes, the pain gives much discomfort in continuing the computer work.

Milk consumption:

1. These negative effects are almost overcome by the consumption of full cream milk at night just before going to bed. Half a glass full cream milk was consumed after 4 hours of dinner and just before to lie on bed. Next morning, higher energy levels, positive mood, increased focus and concentration were observed. This effect was observed with all dairy products such as milk, yoghurt, butter and ghee except cheese. However, the pain component stayed there. Not much change was observed in the hand pain, finger pain, low back pain and buttock muscle pain.

Hand pain and meat consumption:

Due to heavy laptop use with mouse, I used to get right hand pain around the wrist, palm and fingers. With rest, this pain usually subsides. Sometimes, the pain is severe. Nowadays, I am not taking any multivitamin. But, I am consuming two eggs per day one in the lunch and dinner. Still, the hand pain is there almost everyday. With rest (not using laptop and mouse), the pain disappears. After consumption of meat (mutton, beef and chicken with mutton being the most significant influencer and chicken the least), I have observed that the pain subsides significantly. Also, this hand pain also subsides after consumption of calcium, magnesium, zinc tablet. These observations suggest that the meat products may contain these minerals and might offer the reduction of hand pain. However, the amount of calcium and zinc in mutton and beef meat are not really that much. So, alternatively, based on my previous experiences, the role of vitamin B12 may be suspected here as meat products especially mutton and beef contain more B12 and might offer some neurological cure to hand pain.

Update on hand pain 2 July 2020:

The hand pain decreased very much after I stopped egg consumption for two days. I am taking osteocare tablets and diabetone capsules every day. Need to analyse which one has reduced the hand pain.

Update on hand pain 25 July 2020:

I have taken magnesium at night after dinner (200 mg of magnesium from vitabiotics brand; They have not mentioned what form of magnesium is present in the tablet) for last few days and found my muscle pain and hand pain decreased substantially. However, the focus and concentration decreased very much with magnesium consumption at night.
