Discomfort and Swelling in Left Nipple: A Concern
About five nights ago, I observed that my left nipple had become swollen and sensitive when I touched it. I also noticed a yellowish crust, often referred to as a scab or hardened plasma. Currently, there is notable inflammation and discomfort, but no signs of bleeding or discharge are present. I felt it necessary to share my situation, especially since the appearance seems concerning. I’m hopeful that it’s not a serious issue. For context, I recently discontinued finasteride, suspecting it might be linked to gynecomastia symptoms. Medications I’ve been taking include 1mg of finasteride for hair loss over the past year. Additionally, I have been on Telmisartan and metformin for a much longer duration. In terms of my recent activities, I have engaged in sexual activities, which included a partner stimulating both of my nipples.

It sounds like you’re experiencing discomfort and swelling in your left nipple, accompanied by a yellowish crust. These symptoms could be linked to several factors, including skin irritation, hormonal changes after stopping finasteride, or even an infection. It's understandable to feel concerned, but let’s focus on practical steps you can take to address this condition while monitoring it closely.
Explanation
-
Possible Causes: The sensitivity and swelling in your nipple, particularly after discontinuing finasteride, may suggest hormonal shifts leading to gynecomastia (breast tissue enlargement) or irritation from physical stimulation during sexual activities. The yellowish crust might indicate a mild infection, irritation, or a skin condition.
-
Current Symptoms: Since there’s no bleeding or discharge, and you’re not experiencing severe pain or fever, the immediate concern appears manageable. However, it is important to monitor your symptoms to ensure they don’t escalate.
Next Steps
-
Self-Care:
- Avoid Irritation: Refrain from any activities that may irritate the nipple area (like further stimulation or tight clothing).
- Maintain Cleanliness: Gently clean the area with mild soap and water daily, pat dry carefully.
- Use a Moisturizer: If dryness is a concern, consider applying a fragrance-free moisturizer to help soothe the skin, but avoid directly applying it on any open wounds.
-
Monitor Symptoms:
- Keep an eye on the swelling and discomfort. Document any changes, such as increased redness, pain, or the development of new symptoms.
- If the yellowish crust worsens or you notice any discharge or bleeding, it may indicate an infection that needs more attention.
-
Know When to Seek Help:
- Contact a healthcare provider if symptoms persist beyond a week, worsen, or if you develop fever or significant pain. This is especially urgent if any new symptoms (like discharge or severe swelling) occur.
Reassurance
It’s good that you’re attentive to your body, and many skin irritations or hormonal adjustments can resolve with proper care. If you have further concerns about hormonal changes due to your medication or other aspects related to your health condition, please feel free to share. Your well-being is an important priority.

Post-Stress Hormonal Changes and Menstrual Cycle Insights
My wife, aged 27 and weighing 55kg, had a rather lengthy menstrual cycle lasting three weeks back in early June, which understandably caused some concern. During that time, she was experiencing heightened stress due to excessive exercise and emotional strain. We consulted a gynecologist, and an ultrasound revealed nothing unusual—no cysts or fibroids were detected. Fortunately, her bleeding ceased around June 9. Since that episode, we've relocated to a new country, allowing us to de-stress and adopt a more relaxed lifestyle. Fast forward to over three weeks later, and she began her next menstrual cycle on July 1. This time, her cycle resumed a more typical rhythm, starting with light spotting, escalating into heavier bleeding, and eventually tapering off. Notably, there was one day when she experienced a complete cessation of bleeding, only for it to return the following day. As of today, we are on Day 8 of this cycle. The bleeding has diminished once more, and she has not experienced any pain, dizziness, or other troubling symptoms. Historically, her menstrual cycles were quite regular before these incidents. Could this fluctuation still be a result of hormonal adjustments following stress? Has anyone else experienced similar delays in cycle regularity after a stressful event? We’re seeking reassurance or perspectives from others who might have been in a comparable situation.
Advice Needed on Recovery After Calcaneal Surgery and Mild Osteoporosis
Hello all, I'm a 20-year-old male currently in the process of healing from two surgeries on my heel bone (calcaneus). Initially, I had an aneurysmal bone cyst, and during the first operation, my doctor discovered that it potentially extended further than anticipated. This led to the recommendation of a follow-up CT scan, which confirmed the situation. Consequently, I underwent a second procedure on May 5, 2025, to completely excise the cyst. After the surgeries, I had to be on strict bed rest for over a month and a half. My cast was taken off on June 23, and I was instructed to start bearing a little weight using a walker. About ten days later, I received the go-ahead to put full weight on my foot. However, a CT scan conducted about 15 days post-cast removal indicated that I am experiencing mild osteoporosis, likely as a result of the prolonged immobility. To aid in my recovery, my doctors have prescribed a Denosumab injection to bolster my bone health. The hospital's estimated cost was ₹20,000, but a consultant from the facility mentioned he could facilitate obtaining it at a different hospital for roughly ₹10,000. I would appreciate any advice regarding this as well. Currently, I am undergoing physiotherapy. While performing certain movements, particularly when my ankle flexes, I sometimes encounter sharp pain or a tingling sensation either around my heel or in my toes. Additionally, mild swelling and discoloration of a red-brown nature persist, although I do not experience consistent pain at rest or with gentle movements. Here are my inquiries: 1. Has anyone here undergone Denosumab treatment? How many injections were required, and did you observe improvements in your recovery process? 2. Should I be significantly concerned about mild osteoporosis in my current situation in terms of long-term effects? 3. Can anyone offer advice on how to manage heel sensitivity while bearing weight or suggestions for alleviating recovery-related discomfort? 4. For those who have had a similar experience with bone cyst removal, how long did it take before you were able to walk normally again? Thank you so much for your assistance! I would greatly value your insights or personal accounts.
Experiencing Fainting Spells?
Profile: 17 years old, Female Conditions: Diagnosed with chronic migraines, PTSD, anxiety, depression, seasonal allergies, and an allergy to EEL. Medications: Currently on Benadryl, Tylenol, and Claritin. Note: I cannot take Sumatriptan as I am six months pregnant. Supplements: Iron and B12. Substance Use: Prior to pregnancy, I utilized cannabis edibles for pain relief. For nearly two years, I have been facing issues with fainting. These episodes often lead me to the emergency room; however, every time my vitals check out as normal. My vitamin levels are adequate, my blood sugar is stable, and I am well-hydrated. Yet, despite this, the reason behind my fainting remains a mystery. The onset of these spells can be unpredictable. Occasionally, I experience brief dizziness and blurred vision just before fainting, but other times I have no symptoms and suddenly find myself on the floor. A battery of tests, including EKGs and EEGs, have been conducted, but they have not provided any answers. I'm feeling lost regarding this situation and unsure about whom to consult or what additional tests I should request. It's worth noting that this condition began prior to my pregnancy, so it cannot be attributed to that.
30M - Concerned About Blood in Semen
Hello everyone, I’m feeling quite anxious right now. I've never experienced any health issues like this before, but I've noticed blood in my semen on two separate occasions: once last week and again this week after I avoided masturbation due to feeling distressed. While there was no discomfort during ejaculation, I did have some pain and sensitivity afterward. I visited urgent care over the weekend, where they ruled out a urinary tract infection. I'm now making it a priority to see a urologist as soon as I can. Will I be able to enjoy a normal sex life again? I've been browsing posts on Reddit, and it seems like this might be a long-term issue… is it possible that I might have to give up on my sexual desires permanently? This is overwhelming…
Flattening of Breast with Intermittent Pain - Is Immediate Attention Needed?
I am a 44-year-old woman, measuring 5 feet 9 inches tall and weighing 180 pounds. I identify as Caucasian and reside in the United States. For the past couple of months, I have been experiencing a concerning change in my left breast, which has noticeably flattened on its outer section. At first, I didn't think much of it, but I have experienced pain on two occasions. The first instance was slight, while the second struck me late at night with considerable discomfort. Additionally, I've noticed that this breast seems somewhat denser than before, although there are no discernible lumps. My medical history is generally unremarkable; I am mostly healthy aside from carrying excess weight. It's worth mentioning that my paternal grandmother had a history of breast cancer. Currently, I am not on any medication. I’m in search of a physician but have found that the earliest appointment I can secure with a well-regarded specialist is in late August. In light of my symptoms, is this wait excessive? Would it be advisable to seek out imaging services sooner? Thank you for your insights!
