<s>[INST] I have been experiencing tingling sensation on my inner thighs and inner shins on and off for several months. There is no sign of any rash. I also experience a stinging pain after urination and the foreskin is always slightly red and uncomfortable. In case it may be relevant I also have quite a lot of lower back pain. Any help much appreciated!
