after applying Salactin paint on the face,Dark spot appeared. Please reply

I have an itchy scalp, dandruff and experience pain in my hair roots. After meeting a skin doctor I have been using an overnight lotion twice a week, shampoo and multivitamin tablets prescribed by her since last ten days. Right now I have developed some swellings in the back of my head on the right side behind my ear on the hairline. It is extremely itchy around that area since last three days. This seems to be a recurring symptom and it appeared during summer season in the last two years also. Sometimes I get headaches that takes place on the right side of my face and head, and last for 24 hrs. I was diagnosed with cervical spondylosis two years ago. After my recent health checkup my thyroid is on the margin at 5.71. What should I do? Which doctor should I see?

Hi.. Im 24 yr old male. i have an habit of masturbation. i think in my school 8th class i did masturbation first time. After a year it became a habit for me. i’m very much ashamed of having this habit. After doing masturbation, I hate myself that I cant control it. I think to control doing next time, but finally again I do it. From that time to till now I cant stop this habit. So more or less I masturbate twice a week anyway and in rare cases thrice a week. Accidentally during my college time I watched some programs in tv saying that masturbation causes not able to do sexual intercourse with partner. It causes not able to give a baby after marriage. After seeing that type of programs I got very much afraid of my life. Before two years I did laser eye surgery. Before surgery they did all pre-test for me. Then they said that your nerves are weak so we need to do two more extra test. After that extra test doctor said that we can do the surgery there’s nothing problem regarding the nerve weakness. I Think may be its family gene problem having nerve weakness. Maybe your grandfather too could had nerve weakness in his life. And now after two years of eye surgery I didn’t face any problems. As doctor said my nerves are weak in my body from my small age.After masturbating all these days I feel my nerves got more weak than before. I don’t know whether it is due to masturbation.But nowadays after masturbation I get head pain back side sometimes and not everytime. Anyway I feel nerves are weak in my body.I’m afraid very much that I cant do sexual intercourse with my partner if I get married. I’m afraid that I cant make my wife pregnant after my marriage. Please help me can I make a baby with sexual intercourse after my marriage? Do I’ve to get any treatment regarding sexual or regarding my nerve weakness or do I’ve to check whether can I make a baby with good sexual intercourse??

Hello Doctor this is Emmanuel Nice to hear from you, actually my skin is not extremely very dark but compared to a 'White skin' it is, I'm not very pinkish, but I'm fairer than the other dark people. If I come under bright lights I look fair I don't know what medicine changed my skin colour as I'm not good at medicine. My toes, feet, neck, Hands and other private parts like me penis are also dark, I've tried the Vitamin C Calamine lotion Multani mitti allovera face wash drank water used sunscreens accordingly these only work to certain extent and I feel these are meant for people who are looking to improve their complexion and not to restore the original skin colour. I actually look like a South Asain. It took some time may be about a month my complexion became dark. I don't have any other symptoms except for skin darkening and don't have any dark spots either Please advice me with the best medicine. Thanks & Regards Emmanuel
