Neurological Causes
Pudendal Nerve Irritation/Entrapment:
The pudendal nerve and its branch, the dorsal nerve of the penis, are responsible for the glans's sensitivity. Irritation, compression, or entrapment of this nerve can lead to neuropathic pain, numbness, tingling, or burning in the penis, often at the tip.
Pelvic Floor Dysfunction:
Hyperactive or tight pelvic floor muscles, such as the bulbospongiosus, can cause pain to radiate into the penis by compressing the pudendal nerve.

Genito-Pelvic Dysesthesia (GPD):
This involves abnormal sensations in the glans, which can include pain, itching, buzzing, or throbbing, and may be linked to certain medications or psychological factors.
Other Potential Causes
Infections:

Balanitis (foreskin and glans infection), urethritis (urethra inflammation), or sexually transmitted infections (STIs) can cause pain.
Peyronie's Disease:
This condition involves fibrous scar tissue forming inside the penis, leading to pain and curvature.

Injury:

Direct trauma to the pelvic area can cause nerve irritation or muscle damage.

Other conditions:

Less common causes can include penile cancer, priapism (prolonged erection), or issues with the urinary tract.

This is what short googling found - I would suggest that you go to a neurologist for consultations. As you can see there are several different neurological causes of pain in that area.
Wishing you the best of luck.
