The basic thing is that cause should be removed. 'NIDAANPARIVARJANAM' is a saying in Ayurveda in Sanskrit language. Means: Avoid the cause.

Compression should be removed - by physio, by medicine which strengthen muscles/ nerves to counter pain, to avoid degeneration etc., by surgical methods etc.

Surgery should be the last resort.

Nerve damage already done is little difficult to recover. Yoga, deep breathing, some herbomineral Ayurvedic Medicines may help recovery. But not much studies are scientifically documented.

Initially Harsingar plant leaves' decoction (night Jasmine), if used orally for few weeks will show dramatic changes. That's what we give to our patients in India. Some other medicines which are permissible in India like yogender rasa and Brihat Vata Chintamani Rasa etc, nux vomica based Vishtinduk vati, muscle strengthening by Mahavishgarbh and Mahanarayan Ayurvedic Oil maasage and hot fomentation thereon have been used successfully in Indian Ayurveda institutes to correct such problems.

Similarly erection related problems may be addressed by particular local penile applications. But all depends on your doctor's choice and exposure to Ayurveda experience and in which part of globe you live.

Hope it helps.
