Good news to read that your continence is already slowly returning, that's quick and may bode well for your future recovery.
What size Tadalafil were you initially prescribed, and, do you have a repeat prescription?
From my experience Tadalafil/Cialis was prescribed as a daily 5mg tablet. The purpose was to promote blood circulation around the body and it would help where any surgery had maybe made blood flow restricted or difficult.
8 x 50mg Sildenafil/Viagra were prescribed to me for, as Lyn states above, "event" tablets, IE when you want to have sex.
Important to note that none of the tablets are guaranteed to work for all.
With regard to medication and recuperative kit, pumps for example, it seems common that if you don't ask you don't get?
As stated above some pumps can cost £400. When I asked my GP for a pump, he very honestly told me he knew very little about them and the supposed benefits, and asked me to justify the outlay. So I prepared a letter outlining the business case for me to have a pump. I got one, and the meds I asked for. In the meantime I'd bought a pump online that did the same job, just not as fancily.
Lovehoney have a sale on at the moment. I'm sure there are other sites out there.
Anyone in your position has a choice. Wait for the NHS to kick in and supply what you need. get some of what ever to is privately, use it and the positive results can then be presented to your NHS provider to require them to fund your need.
In the meantime, exercise the area as much as you can to promote blood flow.
Atrophy! The one word that strikes fear into us all. I have no idea how and when tissue becomes atrophied, and beyond recovery.
And I was never prepared to give it some time to find out. If it were me, and it once was, I would do everything I could as soon as I could to get blood flowing, exercise, and get the kit and there medication that may help me.ATB
