Hello, None of the issues you are suffering from are severe enough that you need to feel worried excessively or feel depressed. Lets us go through your problems one by one. For PCOS, you should consult a gynecologist and get your blood tests done for hormonal levels. You might also need to go for Ultrasonography (USG). After results, you might have to start on hormonal medications to regulate hormonal levels and menstrual cycles. If you are getting married soon and not planning pregnancy right away, then medicines of PCOS will also help you for birth control as birth control pills. Nerve weakness may be due to deficient vitamins. Healthy diet with fruits and vegetables will help you. Do no miss out on dairy products. Stress, anxiety, headaches are very common and natural when you are going to get married soon. Try to relax and enjoy this phase of life. Think positively even if it takes an effort to do so. This phase will come only once in life so enjoy fully. Sleep adequately and eat healthy. You can take painkillers like Tylenol available over the counter for occasional headaches. Exercising regularly will release endorphins in your body that will reduce anxiety and elevate moods. Yoga and meditation can help, too. Neck stiffness may require you to change your pillow and exercises advised by physiotherapist. You can also apply Diclogesic Gel or spray (Volini) over the painful area. Taking Dan-MR or Hifenac-MR will also help you to relax muscles. Premature orgasm is a frustrating problem that many women feel. However, sexual intercourse is different than masturbation in many ways and you might not feel this trouble after getting married. You can do pelvic exercises to tighten the muscle in the pelvic area. Whenever you are free during day, tighten the pelvic muscle, hold it for some time and release it. It is the same muscle that you release during urination. I hope this information helps. Thank you for choosing HealthcareMagic. I wish you a very happy married life! Best, Dr. Viraj Shah
