Hello,
I have studied your case.
As there is
osteoarthritis of your knee.
You can start cartilage protecting medication like chondritin sulphate, that you need to take for couple of months.
You can start percocet instead of oxycodone.
If required MRI knee can be done and if there is severe destruction of menisci then arthroscopic shaving can be done.
Physiotherapy like
ultrasound and tens will help, along with knee exercises.
Due to compression of this
nerve root there is tingling numbness in your leg and pain associated with it.
For these symptoms
analgesic and neurotropic medication can be started.
Till time, avoid lifting weights, Sit with support to back. You can consult physiotherapist for help.
Physiotherapy like ultrasound and interferential therapy will give quick relief.
Core stabilizing spine exercises will help.
I will advise to check your vit B12 and vit D3 level.
