Suggest Treatment For Tingling Sensation In The Feet And Fingers

I am 58 yrs. old male 5ft. 10 inches tall weighing 75 kgs develop pain in the left chest and it percolating down the left arm and sometimes mild pain in the left hand middle finger and next finger to it.This I feel when I talk over phone for long hours with voice loud and when I get tense.I do brisk walk in the morning for 45 mts. covering a distance of 5 kms.I don,t feel anything while walking or while doing any physical activity.It only happening when I talk over phone with voice loud or when I engage in arguements over phone.Some 6 yrs. back I consulted a cardiologist for the same reason and on doing all the tests and TMT for half an hour at high speed doctor said no problem and if I continue with it I have to do other tests.It happens rarely when I get tense and talk over phone.I got tense 10 days back and I develop it in the morning or any day time during day.When I am not at tense it is not there.I checked the BP and it was normal. I don,t have cholesterol ,LDPL,Triglyceroids problem and all these are with in limits.My sugar is at border and 2 months back it escalated to 180(fasting) and doctor gave me AD GLIM 2 tablets and I stopped a month back.That time I was tense and developed tingling sensation in the feet and fingers..Doctor has given tablets for nerve regeneration also that time.Now after getting tense I have developed tingling sensation again.It comes any time during day and goes off sometimes.Again I have started taking AD GLIM 2 since 4 days.I feel it is because I got tense and that day talked over phone for an hour.Earlier this pain goes off with in a day or two. Now it is there since 10 days but intensity is not as much which I had on the first day.When I develop pain because of talking and I feel uneasy and get tired and unable to do any work.Pl. advice me
