Hi,
Notd your history of dry scaling of testicles which in fact is of the skin I suppose and tender penis. You are using moisturising lotion for scrotal skin.
I think you have dermatitis of the scrotal skin and the most proper diagnosis can be had by consulting your
Dermatologist as there are numerous causes of this.
Scabies,
atopic dermatitis, allergic to soaps or so dermatitis,
Psoriasis and so on can cause such problems.
Tender penis can be caused by any inflammatory process going on
in the structures in penis like Peyronie's disease and so on.
Hence consult your
Urologist for clinical evaluation, examination and investigations to know the exact diagnosis and have proper management.
Avoid sex till the penis condition is diagnosed and well treated.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. T. Chandrakant, General Surgeon
