Low blood pressure. Or test is required?

I was feeling tingling and numbness in jaw and tongue and later on it started in hands and feets, it made me started feeling dizzy. I went to govt hospital they checked BP, it was around 80/50. They admitted me and incharged a bottle of glucose something. After that my BP went to 90/70. After that I slept feeling some numbness in hands and feets too. Next morning my BP got 120/80. I went to checked by a private doctor. He has given me livogen, A2Z tablet and told me to not worry about this. Numbness and tingling are not there but still I am feeling weakness and blurred type vision (sometimes). It's been two days since the low blood pressure. Note : I had taken some couple of ayurvedic medicines for allergies as my IGE level is high. After the second dose this all happened. I am also monitoring my Spo2 and heart rate. (Both are okay). Last year I had done almost all tests, all were normal. Will this weakness stay for few more days or any other treatment or test is required ?
