Hi guys, what's up?

I'm writing to you my story which has similar sympthoms from yours. First I'm describing my current symptoms. Then below some history of threatments and of when I started to feel like this.


Current Symptoms:
- Penis' skin with the same previous changes: different color, thinner skin
appearance and thicker / apparent veins, nerves more apparent. The nerve of the underside of the penis, it seems more salient and "hard" when the penis is erect.
- It seems like there's a division in the penis - In one part is normal
color and appearance and the rest is not.
- Heavy penis sensation, always pointing downwards and weighing down.
- Areas where previously felt itchy and where I used the pastes, are those
that sensitivity is lost. I can't feel the itching in these areas since I
lost sensitivity.
- Almost total lack of sensitivity in the penis body at the topside. The glans
has almost no sensitivity. Underside of the penis with greater sensitivity, but not 100% normal.
- Besides the penis, I feel that I lost sensitivity of the innermost part
of the buttocks or **** (feel that control how to eliminate gas / fart has
changed, for example, is difficult to explain).
- Loss of erection upon waking up accompanied by urination urge. I have now no erection in the morning when I wake up and the urge to urinate is
non-existent or very mild.
- Urinating: With the erect penis, must make great efforts to urinate. With
the soft penis, there is not the same sensitivity and control. Penis always
down.
- Erection: Occurs but needs greater stimulation than before to occur. In
closing the stimulation, the erection ends much faster than before.
- Ejaculation: It happens, but without the same pleasure. When it comes out
of the penis, it seems that comes "through the penis" with greater
difficulty and not as much pressure as before.
- When I force the muscles of this area, like if I was going to urinate for
example, I can't feel or control the penis.
- Pain in the lower back, especially on the right.
- In the past weeks, I started to feel tingling sensation on the right
foot. Rarely, pain on the sole right to get up and walk after sitting or
lying down.
- Pain when you press with your fingers a portion of the right leg muscles
on the lateral aspect of the buttock.
- No sexual relations since end of 2014, when the symptoms in the penis
started. In a relation with girlfriend since 2012 and she has no similar
symptoms.

History of Symptoms:
- Since 2011: Itching in the groin area, between thighs and scrotum, also
inside the buttocks and between scrotum and buttocks. I never did any
treatment related to this. I'm not sure what could have caused this.
- September 2014: Itching in the penis body with a white spot circle
- From September 2014 until March 2015:
1. Used Canesten paste in penis, inside the buttocks and I took water
bath vinegar in the penis only. Vinegar helped to "dry" the white spot and
it started to become red and then to come back to normal color of skin.
2. Continued to use for a few more months in penis, inside the
buttocks and I took water bath vinegar in the penis only, but if I stopped
using for a few days, the skin became red and itching again.
3. March: Doctor examined and told it was related to fungi. I used Icaden/Isokonazol) in penis and inside the buttocks.
4. It got better and I stopped using all pastes and vinegar bath.
- April 2015:
1. Started exercising at the gym, with weight lifting.
- May 2015:
1. Red skin area and itching started again.
2. Used Icaden - Isokonazol for 2 days on penis and inside the
buttocks.
3. Two days later, after going to gym, I took a shower and started to masturbate. I felt like my penis was under anesthesia. I couldn't stimulate it normally and the sensation was the same as if I was recovering from anesthesia, really doing effort to feel it and be able to unirate.
4. On following days, I also noticed that I didn't have the same
control to fart (it's hard to explain).
5. Suddenly, the itching completely disappeared, in the areas where I
lost sensation (in penis and between buttocks).
4. After that, it never came back to normal.
- May/June/July 2015:
1. I used Imacort, prescribed by Dermatologist. No changes in
the symptoms.
2. I used Protopic for 2 weeks as indicated by Urologist. Skin got
better, but the sensation was the same.

Examinations:
MRI, EMG, Blood (for testosterone), Urine, Electroencephalogram. Everything so far, normal. The only thing found on MRI is Tarlov Cyst and a disk that is 3mm not in the correct position, but it's not pressuring any nerves.

I'm really desperate, as probably most of you are. Thank you for the space and sorry for so many words. Hopefully one of you will have something else to indicate.
