hey everyone
I am 21 year old male and I have recently encountered some problems.
As of two weeks ago I had some slight right flank pain back by my kidney and is kinda tender to the touch. The pain/discomfort hasnt really gone away. I have also had left side flank pain also. Most of these pains are constant but arent that bad.
I also have been having lower back pain and a weird sensation around my tailbone which has come and gone these past two weeks but can be very uncomfortable. I also have developed a pain when sitting down especially my left butt cheek. I have had a hemrriod for about 2 or 3 years now and has bled in the past like a tiny tiny drop but I havnt seen that in a long time and it was a bright red and it has never bothered me.
I havnt noticed any blood in my stool or anything.
I even went to the ER and they did some basic blood tests which were normal and even did a CT Scan of my abdomin area but didnt see anything.
I also went to my regular Dr. who did some more blood test(still waiting to hear results) and also did some XRAYs but didnt see anything on those also. These flank pains have been going for two weeks now and the back and butt pain has been going for the past week.
I also havnt been going "poop" as much as I use to. Now its about once a day compared to two or 3 times before.
I am freaking out that it is CC because I read somewhere that if your tailbone is having that sensation it is a good indication of CC. Can anyone help me out with some answers? Thanks!
