Toprol-XL and great shape

I have crazy muscle pain or sharp stress like pains in my arms and hip joint - I take 12.5mg toprol xl - i have notice some weight gain - I know our Doctors are not the same, but prescriptions are the same - I feel like the doctors are brain washed by the durg companies, getting some sort of kick back. I listen to my heart Dr. yet he doesn't listen to me Toprol xl does cause changes to peoples health.
After reading about 20 listing and viewing over 18 web sites just about toprol xl - we are not crazy thinking this MED has bad side effects.
I'm in great shape, I work in construction & work long days and move heavy items daily. My heart problems are less than most, yet this silly pill has caused more dis-comfort than I was in before, I started taking It. I will slowly take myself off toprol xl.
I'm going to try to find a natural way to find small dose beta blocker, does anyone else know of any natural beta blockers?
Stay well and enjoy life to fullest
