I was a little confused by your question. What color is the discharge that you get after your period? Is it colored or clear? Why does it disturb you a lot? Is that because it invalidates your wudu? What medication exists for controlling discharge?

The simple answer to your question is no. It is not permissible to masturbate to reduce your discharge. On the contrary, I fear that your masturbation may be causing it to worsen month after month. I am sure that if you stop this behavior, your situation will improve physically and spiritually.

This is my take on your situation. I believe that you are experiencing madhy, which is arousal fluid, and the “disturbance” you speak of is sexual tension. Then I think the “relief” you describe is achieving orgasm, hence the instant relief.

Please know that it is worthwhile to protect yourself from this addiction and make repentance for your actions. I pray that you can cease this behavior to preserve any intimate experiences for marriage. I have not heard of masturbation as a cure for any medical problem except for this:

Is Masturbation Permissible for Medical Reason? (Shafi’i)

Please consult a doctor about this if I am missing something, and don’t hesitate to follow up.

May Allah Most High grant you the best of this world and the next.
