Hello,
Thanks for posting your query.
A magnesium supplement is not likely to cause a knee pain. Magnesium supplementation rather helps with such minor pains in case the pain is due to calcium deficiency.
At your age, osteoarthritis is the commonest cause of both knee pain. You can get X-ray of your knee joints done to know the exact cause.
Meanwhile you can start taking Tablet Tylenol ( Acetaminophen) Double Strength after breakfast and after dinner. It is suggested to add calcium supplements 500mg each twice daily. This will take care of your mild symptoms in 3-5 days.
You can start with walking and aerobic fitness exercises, quadriceps strengthening, patellar tapping, lateral heel wedges, etc- under the guidance of your physiotherapist.
A Big No to Stair case, squatting postures, any chair which has a sitting platform lower than your knees.
Knee brace can also be used for an earlier and prolonged relief.

I hope this answers your query.
In case you have additional questions or doubts, you can forward them to me, and I shall be glad to help you out.
Please accept my answer in case you do not have further queries.
Wishing you good health.
Regards.
Dr. Praveen Tayal.

Hello.
Thanks for writing again.
You can continue taking the magnesium supplements as prescribed to you by your physician.
You can take 2 tablets of tylenol twice daily after the meals.
Walking on the treadmill will be helpful but only after the acute pain in the knees has subsided.
Hope my answer is helpful.
Do accept my answer in case there are no further queries.
Regards.
