Player Will not take any damage!

I've been working on a project for a while now, and have tried to implement the ability for the player take damage, and nothing works! I have done the exact same thing to my enemies and it works for them to take damage and die, but the player won't take any damage. Please help, thanks.

PlayerHealth Script:

 public int playerHealth = 15;
 public int playerDamage = 2;
 public float flashSpeed = 5f;
 public Image damageImage;
 public EnemyMovement enemy;
 bool damaged;
 public Color flashColour = new Color(1f, 0f, 0f, 0.1f);

 void OnCollisionEnter(Collision col)
 {
     Debug.Log("EnterCollider");
     if (col.transform.tag == "EnemySword")
     {

         damaged = true;
         playerHealth -= 3;
         Debug.Log("DamageTaken");
         if (playerHealth <= 0)
         {
             Destroy(gameObject);
         }
         damaged = false;
     }
 }

 void Update()
 {
     //If the player has just been damaged...
     if (damaged)
     {
         // ... set the colour of the damageImage to the flash colour.
         damageImage.color = flashColour;
         Debug.Log("FlashTrue");
     }
     // Otherwise...
     else
     {
         // ... transition the colour back to clear.
         damageImage.color = Color.Lerp(damageImage.color, Color.clear, flashSpeed * Time.deltaTime);
     }

     // Reset the damaged flag.
     damaged = false;
 }

}

Swing Script: { Animator anim; bool didSwing = false; public EnemyMovement enemy; AudioSource playerAudio; public AudioClip SwordSwing;

 void Start()
 {
     //get the animator
     anim = GetComponent<Animator>();
     GetComponent<AudioSource>();
     GameObject.FindGameObjectsWithTag("Enemy");

 }

 // Update is called once per frame
 void Update()
 {
     //call triggers via keypress - you can also assign them via the preset inputs
     if (Input.GetKeyDown(KeyCode.Mouse0))
     {
         anim.SetTrigger("swingA");
         didSwing = true;
         Debug.Log("swapTrue");
         //playerAudio.clip = SwordSwing;
         //playerAudio.Play();
     }
     if (Input.GetKeyDown(KeyCode.Mouse1))
     {
         anim.SetTrigger("swingB");
         didSwing = true;
         Debug.Log("swapTrue");
         //playerAudio.clip = SwordSwing;
         //playerAudio.Play();
     }
     if (Input.GetKeyDown(KeyCode.W))
         anim.SetTrigger("Run");
     if (Input.GetKeyDown(KeyCode.Space))
         anim.SetTrigger("Jump");

 }

 void OnCollisionEnter(Collision col)
 {
     if (col.transform.tag == "Enemy" && didSwing == true)
     {
         enemy.enemyHealth -= 2;
         if (enemy.enemyHealth <= 0)
         {
             Destroy (col.gameObject);
         }
 
       didSwing = false;
     }
 }

}

EnemyMovement Scipt:

{

 public Transform Player;
 public int enemyHealth = 10;
 public int enemyDamage = 3;
 public int MoveSpeed = 4;
 public int MaxDist = 10;
 public float MinDist = 1f;
 bool didSwing = false;
 public PlayerHealth player;


 Animator anim;

 void Start()
 {
     //get the animator
     anim = GetComponent<Animator>();
     GameObject.FindGameObjectsWithTag("Sword");

 }

 void OnCollisionEnter(Collision col)
 {
     if (col.transform.tag == "Sword" && didSwing == true)
     {
         enemyHealth -= 2;
         if (enemyHealth <= 0)
         {
             Destroy(col.gameObject);
         }

         didSwing = false;
     }
 }

   
 void Update()
 {
     transform.LookAt(Player);

     if (Vector3.Distance(transform.position, Player.position) >= MinDist)
     {

         transform.position += transform.forward * MoveSpeed * Time.deltaTime;
         anim.Play("Run");


         if (Vector3.Distance(transform.position, Player.position) <= MaxDist)
         {
           
             
             anim.SetTrigger("swingA");
             didSwing = true;
             //Debug.Log("EnemySwingATrue");

             anim.SetTrigger("swingB");
             didSwing = true;
             //Debug.Log("EnemySwingBTrue");

         }

     }
     

 }

}

The debug logs within the Health script tell me that the enemy sword is entering the collider, but no damage is being taken.
