Suggest Alternative Medicine Of Vicodin For CTEPH

I am 62 year old male. My underlying condition is CTEPH,began some 14 years ago. This has led to a number of conditions I suspect, such as first stage heart failure, 2nd-3rd degree kidney failure, osteopenia, etc. Currently taking 10 mg vicodin every 6-8 hours to deal with constant widespread muscle and joint pain. Are there any alternatives? TIA, Phil
