I have dark patches on my collarbone. It started over a year ago, after I had prickly heat in that area ... Initially there was one small discolouration on one side, and after a few months, there was a very small patch on the other side. Now the patches have become larger (about half an inch), and it s spreading. What do you think has caused this problem, and what do propose as a treatment?
Hello Fauna.hasn ain, Welcome to Chat Doctor forum, It seems you have taken the dark patches on your skin quite easy. It is increasing in number because you have been neglecting it since a year. You have sensitive skin. Skin discolorations and patches take time to return to normal. They took almost a year to seek your attention so just have a little patience they will go away gradually. You should firstly take heed to what you eat. You should increase your dietary intake of vitamin B and E. You can even take nutritional supplements containing vitamins and minerals. Keep yourself well HY Chat Doctor.  Take 1-2 liters of water each day, plenty of fruits, juice and soups. Add cereals, legumes and dairy products in your diet. You do have the option to consult a dermatologist. The patches and discoloration can be because of some allergy. You need to investigate and see what are the things around you like pollen, pet animals, allergy causing plants and foods to which your skin is sensitive and reacts adversely. Just stay away from them.  It can also be due to sun burn, reaction to some type of jewelry, fur or leather. It can also be due to some bugs in your room or war
