I do catherization each 4-6 hours.

I am having problem in catheterization for more than two months now; the catheter cannot pass the sphinter in about half of the times I try to Cath in.

I went to the doctor and gave me muscle relaxing medication; there was a little improvement in cathing but not 100%. The doctor mentioned the botox as another solution.

So I want to ask; can botox be used to solve the problem? And what other options?

Please help; this problem caused me a lot of trouble in the last few months
