Suggest Treatment For Clear Penile Discharge

Hi, I often find that when I take my underwear off the material is often damp and wet. Its a clear liquid, and doesn't smell exactly. It is literally like urine, apart from has no colour, and I can often feel when it passes...

To me, I can think of only two possible reasons... I only noticed it after I damaged and fractured my back after accident where I fell off a cliff. The other is the acid levels have changed, I'm not entirely sure... Any solutions and cures?!?!
