I'm sorry to hear you're experiencing premature ejaculation and shin pain during sex. These symptoms can be distressing, but there are ways to address them.

Premature Ejaculation:

• This is a common sexual health concern that can often be managed with behavioral techniques, counseling, or medications prescribed by a specialist such as a urologist or a sexual health doctor.
• Lifestyle changes like reducing anxiety, practicing relaxation techniques, and improving communication with your partner can help.
• Certain supplements and medications may also be recommended by your doctor.

Shin Pain During Sex:

• Pain in the shin area during sexual activity is unusual and may be related to muscle strain, nerve irritation, or circulatory issues.
• It’s important to have this evaluated by a doctor, preferably an orthopedic specialist or a neurologist, to determine the cause and appropriate treatment.

General Recommendations:

• Avoid self-medicating without professional advice.
• Maintain a healthy lifestyle with regular exercise and a balanced diet.
• Consider supplements that support nerve and muscle health, such as vitamin B complex (including B6 and B12), vitamin D, and calcium, but only under medical guidance.

Since you mentioned these symptoms together, a thorough medical evaluation is important to identify any underlying conditions and to tailor treatment accordingly.

Please consult a urologist for the premature ejaculation and an orthopedic doctor or neurologist for the shin pain to get a comprehensive assessment and personalized care.
