After taking any tablet I am getting dizziness & tingling sensation in all over body? What is the reason behind it

I woke up today early morning feeling tingling and numbness in my left palm and fingers. The numbness lasted for a few minutes after that I felt ok. The tingling sensation was mild after that and I could feel it from below the shoulder where our arm starts from, like when we sleep on side, the starting of arm would touch there. I could feel the tingling very mildly even after one and half hours. When I had woken up, I also felt like acidity and anxiety as to will I have heart attack or something but when I checked on BP monitor and oximeter, the BP was 126/76 and pulse rate 63, Oxygen level 98. Please advise.

Hi, l have lately not been able to fall asleep in the night. I fall asleep around 6 7 in the morning no matter how early i go to sleep. This os hapening since one night i had to stay up the entire night for a early morning travel. One night when i am extremely tired i sleep off properly by 10 pm and wake up in the morning.m, next day again i am not able to fall asleep till morning. Tried zolfresh and melatonin on prescription but did not help. What is this condition and how long does it remain. Is it possible to get back to normal without medicines.

I was in depression for more than 7 years. But after curing depression, my sense of touch or feel has gone. For example, if a glass contains hot water & if my finger gets touched accidentally then it takes time for me to realise that it's quite hot & due to this my finger gets damaged or burnt. This is the same in cold water glass as well. So please suggest some medicine so that I may cure my sense of touch or feel as this is giving me a lot of problems in my daily routine.
