Brief Answer:
It is definitely due to medicines that you are taking.

Detailed Answer:
Hello
Thanks for query .
You have been taking Tomsulosin and Myrbetrig for enlarged prostate to improve urine flow and urgency for urination .

Since both these drugs have selective action on bladder musculature and smooth muscles in bladder neck the symptoms that you have like pain in knee and ankle are not due to side effects of these drugs.It may be a coincidence.

Please consult your orthopedic surgeon for pain in joints .

Hope I have answered your query ,please feel free to ask if you have more questions I shall be happy to help you
Thanks and Regards.

I'm confused Dr XXXXXXX Your Brief answer is " it is due to the medicines", than further down your report. You say it "May be coincidence", is it your professional option as a Urologist that the pain in my back, right ankel and right knee, are due to the medicines?? The pain in these 3 areas I described all started at the same time I started taking, particularlly Myrbetrig. I've been on the Tamsulosin for months with no joint pain, but as soon as I started Myrbetrig all hell broke out in all 3 areas at the same time. Please reply

Hello
I am really sorry for typing mistakes .

I would correct my statement state that the joint pain that you have is definitely NOT due to medicines that you are taking.
.
We commonly use both these drugs and have never encountered these side effects .It is not due to professional option .

You may discontinue taking Myrbetrig for couple of days and observe for any improvement in your joint pain.

Thanks and Regards.
