Doctor :   Do you have history of diabetes, thyroid problems in the past?
User :   no
Doctor :   Ok
Doctor :   Let me explain to you.
Doctor :   The red bump you describe probably is an erythematous condition developed secondary to
Doctor :   friction, allergy or an infection.
Doctor :   The former 2 are more likely than the last one.
Doctor :   Keeping the area free from physical contact, avoiding bare finger handling, and local antiseptic creams such as polysporin creams can be used.
Doctor :   If symptoms persist, you may need steroid creams.
Doctor :   However, I would suggest you to consult a dermatologist if the initial treatment measures do not help in resolving the problem.
User :   how long should I give it?
Doctor :   If redness is expected to improve with the measures and the antiseptic creams in another week or so,
Doctor :   but if your symptoms increase or if they last for more than week from now, you may need to consider consulting the dermatologist.
Doctor :   The second black spot is a non concerning problem though.
Doctor :   It may be an area of hyperpigmentation that may have developed due to previous insult such as an minor injury, skin infection or pimple/boil
Doctor :   Alternatively it can be a nevus ( a mole)
User :   do you think the one on my thigh may be a cyst? someone told me thats what it might be and that I would have to go to the doctor
User :   ok
Doctor :   This doesn't need any treatment, and just monitoring.
Doctor :   Watch over the spot, you will need to see the doctor, if you find the spot increasing in size or develop secondary symptoms such as pain, itching, ulceration over the spot.
Doctor :   Have you followed what I have suggested?
User :   yes thank you
Doctor :   Do you have any other query?
User :   I think thats it for now..thank you
Doctor :   Thanks for consulting me.
