I don't think asking a forum such as this will be able to correct the problem. As stated above, you may need some physical therapy, it may be a fit issue. Given the info you have provided, I would certainly start with your doctor to check for any issues before putting miles on the bike. Understand what issues may be there & find someone who understands these issues & how to properly fit you to your bike. A good bike fit takes a good amount of time & the person doing the work will not want you uncomfortable. They will also want you to return to correct any issues that persist.
