Hello,
I have studied your case.
No instaflex will not reduce effect of other medication.
Usually
nerve compression cant be seen on
x ray you may need MRI for this.
There will be age related
spondylitis but if there is any nerve compression then that may need specific treatment.
I will advise you to do MRI spine
Till time, avoid lifting weights, Sit with support to back. You can consult physiotherapist for help.
You may have good relief with
physiotherapy like IFT [Interferential therapy] and TENS[Transcutaneous electrostimulation] along with
ultrasound.
So if possible you can start that.
Also check your vit B12 and vit D3 in your blood.
Hope this answers your query. If you have additional questions or follow up queries then please do not hesitate in writing to us. I will be happy to answer your queries.
Wishing you good health.
Take care.
