Oh well. I do have the exact same issue which have started a couple of weeks ago. I am always in a need of peeing and I also have this strange swollen feeling too… since it all started I have had 2 tests, 2 urinary tract infection tests and both of them were negative. Now I am not having a doctor appointment for next 2 months… I have seen an acupuncturist a couple of days ago and she told me that she believes that this is from the stress and anxiety I am having so there is something that I can do in order to treat it: she advised me to put a bottle of a very hot water between my legs and a second bottle again with very hot water on my lower pelvic area (maximum hot I can resist). I have done this and it did helped and still helps very much! The doc explained it that due to the fact that I have stress, my bladder is pulsating so here is how I have this urge. Besides, I’m on needles from her. she said that I need to forget about caffeine because this is one factor that’s triggering it. she said that I need to drink warm water as much as I can and she also said that I need to eat a lot of vegetables every day and soup too. Yesterday I have decided to ask for other people’s opinions so I have visited a therapist who also said that most likely – this thing it is from an anxiety disorder I have. I have been on depression medication in the past and I didn’t had this symptom. Then I stopped it because it seemed that my anxiety and depression levels dropped down to minimum and they really stayed there for a while, for a couple of months, but now it seems that my anxiety and stress/depression have returned. However, this time I would try to get it fixed in a natural way. So, I really really hope that there would be somebody who is going to find my reply helpful because I know that feeling when you see lots of doctors who are unable to help you and who have no ideas what’s happening to you. I have been taking antibiotics (which we all know that are not so healthy) as a suggestion from those doctors but it was useless. It’s kind of a bad feeling when you know you’ve been taking something that did not helped but have only killed you more… That’s also a bad feeling when you know that there wasn’t a doctor who at least would suggest anxiety as a cause to this problem. I now, finally see a light at the end of the tunnel where the acupuncture and discussing with a therapist really seem to help and I hope it would help further too. as I said, being on anti depressants would most likely help with this issue, I have even read online about people being on them and got helped. I am pretty sure that it is going to help me too, however this means that this is not really an infection or something in this regard. This feeling we’re having may as well be caused by a mental health problem, after all, this is a FEELING! This time I am going to fix it all in a natural way but if I won’t succeed I know that anti depressants are there, especially because they already helped me in the past. I wish you all good luck to deal with this issue and hope that you would find my reply helpful!!
