Hi-had my first biofeedback session today to establish that I'm doing my sphincter exercises correctly ( I am-although squeeze pressures are slightly below normal) to help with urgency. Being anxious about it I decided to try out the propanolol tabs my GP gave me to try last week. I took 4x 10mg-the dose recommended in the leaflet. Anyway, despite being very sceptical about it working-it actually seemed to work pretty well. However, I did notice that I as walked back up the hill to my car after the test that I had to stop several times as my legs just became too tired. I did that walk only about 6w ago and certainly don't remember having to stop. I presume it is the effect of the tablets -only other thing I could think of was that I'm anemic causing shortness of breath. Anyone, have any ideas or tried this medication. I think it worked as well (in this instance, anyway) as diazepam so I'm really happy that I might have found something that helps me.
