Penis Pain and sexual function

Don’t know if this has been covered or not but I’ve just noticed today 3 days post treatment that the tip of my penis has become very red and inflamed, wondered if anyone else who has one had a similar experience and what cream etc did you use on it ?

I think it must be in the blast area of the radiotherapy as the radiographers had to move it from one side to the other when doing the planning scans.

Thanks for any replies or suggestions.

Just wanted to update this thread and expand it slightly as I can’t find many examples of this subject on the forum, so may be useful for future searches.

The original pain turned out to be a slight reaction to one of the creams I’d been applying and I’d managed to get some of it under the foreskin, this quickly resolved once I took more care.

 

Pre treatment I was warned of several possible and probable side effects including probable dry ejaculate long term, possible loss of erections (ED) in the short and or long term and a probable need to be catheterised during treatment.

 

During treatment, although my pee flow reduced quite a bit and was usually uncomfortable, I managed to escape being catheterised. My bladder flet uncomfortable with only a small amount of fluid in there and I was up at least 4 times during the night and sometimes as much as 6 or 7 times.

I did retain erections until towards the end of treatment but from about half way these were really quite painful and would wake me in the night.

My libido really took a hit during treatment but when I did make the effort there wasn’t any fluid produced and there was a significant stinging sensation down my penis just after the dry ejaculation this stinging faded away quite quickly.

 

I’m now 6 weeks post treatment and have just had my clinical review at the hospital.

I still have a completely dry ejaculate and have been told this will probably not resolve, I don’t have the stinging sensation following ejaculation anymore but do sometimes get a sharp pain at the point of ejaculation or sometimes up to 24 hours afterwards or I just have a general discomfort in the penis bladder / prostate area.

My libido has started to return but seems to be a bit up and down (pardon the pun) and the painful night time erections have returned although the pain is now much reduced but does remain.

My bladder capacity has returned to about 80% of what it was before treatment started, I do have some urgency when it’s full and I still have some discomfort when taking a pee but I’m only up once or maybe twice during the night now so that’s much better.

All this I’m told is quite normal for a male following treatment and the pain has been diagnosed as radiation induced urethritis. I was also advised to use a lube during sex as everything will now be completely dry (and it is).

Hope some of this is useful for anyone about to or going through treatment and I’ll update if or when things change.

  • Hello Monty

    Sorry I can't help, I am hoping some of the men on the forum will pick up and give their experience. The radiotherapy can really affect all areas in the 'line of fire' as it were so it may just be a side effect of that.  But that said, it would be worth giving your treating team a ring tomorrow just to make sure there isn't some sort of infection going on.

    Best of luck, and please let us know how you get on.

  • Hi Irene

    thanks for the reply and that looks like a plan. I have only just completed (a week ago) a course of antibiotics for a UTI but it could be an infection ?

  • Hello Monty

    They might call you in to check, but it is worth the trouble in case it needs treatment.  Hope you have recovered from your UTI, very common I'm afraid during and after pelvic radiotherapy.

  • Hi  Like  said hopefully some of the blokes on here will respond. Were you given any creams during treatment like flamigel etc, I can't see any reason you couldn't use them. Sending hugs. Xx

  • Sounds incredibly uncomfortable  , I’d definitely get checked out just in case of infection. Let us know how you get on.

  • HI, Monty ( ),

    Thanks so much for this update, as you’ve said it will hopefully be of some help to someone else  either now or in the future. It’s great to have a man’s perspective here, I think men are a little less likely to seek outside support such as this forum & when they do they tend to read but not to post so much so I’m really appreciative for you updating your original post.  

    I’m really sorry that you’re still experiencing some issues but it’s still really early days in your recovery & some of the side effects just take a little longer to resolve. Although there are many of your side effects that as a female I can’t relate to I can relate to the reduced bladder capacity, as the mother of 2 children my pelvic floor isn’t what it once was & add in the reduced bladder capacity & possible stenosis of the urethra the frequency & urgency of needing to pee can be a real pain! 

    I hope things continue to improve for you.
