### input:
I have a variety of symptoms that may or may not be related, Ill work back in date order so here goes... Most recently I have noticed a smelly discharge coming from my belly button - it has been happening every couple of days at the moment. It leaks a clear smelly fluid. I cleaned it and the cotton wool was yellow after? For the last 5-6 weeks Ive been suffering with a very bloated/ swollen stomach that gives me pain sometimes down low on the left near my pubis and sometimes the pain is high up by my navel. Along with this, I suffered a bout of strong nausea and have been having some pain between my shoulder blades. Also, I have had bad back pain for almost two years now that suddenly started one day when I was walking fast and it has never gone away. It is my lower back (tailbone area can be centered or to the left or right. But always in the same area of the lower back) that seems to get worse and feel tight when I walk at a decent pace. I have received physiotherapy on it, but it did nothing for the pain. I have not seen a doctor or had any tests about my back since the physio.Im wondering if these symptoms are consistant with anything? I am due to have an ultrasound scan soon on my stomach incase its anything to do with my ovaries/womb? I am sick of feeling sick! It seems something new is added to the list each week. Usually, I am very rarely ill. so all these symptoms are starting to get me down as I feel there is no diagnosis in sight. please advise if you can?

### output:

Hi there ~I understand your concerns.  The smelly discharge from your belly button is concerning, and I am thinking that you have an infection there that needs to be treated.  It is not uncommon to have this sort of infection and systemic antibiotics need to be prescribed.  I hope you see a doctor for this as well as the other reasons you have been describing.  I feel like you may also have a urinary tract infection as well as something going on in your lower abdomen most probably your bowels, so a lower GI endoscopy might reveal your problems.  Furthermore, I also feel like you need a pelvic examination and an ultrasound from a gynecologist for the pain in your lower abdomen. I hope this helps.  Take care and have a lovely day!
