Concern Over Temporary Bruise on My 3-Month-Old

7/19/2025, 10:20:16 PMMale25-34

Hello everyone! I wanted to share an experience with my 3-month-old daughter. Recently, while my dad was holding her right after they had been in the pool, I observed a mark on her skin that looked like a bruise. It appeared quite dark initially but then faded away within a few minutes. In addition, she seems to be more irritable over the past couple of days. However, I suspect this might be due to a nursing strike, as she's been able to take a bottle with pumped milk without any issues. She’s sleeping normally, displaying no signs of lethargy, but her fussiness has noticeably increased. Should I be worried about this bruise-like mark, especially since it seemed to vanish so quickly?

It’s understandable to be concerned about any mark on your baby, especially when it looks like a bruise. Based on your description, it sounds like the mark faded quickly, which is encouraging and might suggest it was a temporary issue, possibly from a minor impact. However, increased irritability can be concerning, even if you suspect it’s related to feeding.

Explanation: Bruises in infants can occur from minor bumps and are usually not a cause for alarm, especially if they resolve quickly and the baby is otherwise behaving normally. The fact that she is sleeping well and shows no lethargy is also reassuring. Irregular behavior, such as increased fussiness, can be linked to various factors, including teething, developmental changes, or temporary feeding issues.

Next Steps:

  1. Monitor the Mark: Keep an eye on the bruise-like mark for any changes. If it reappears or if other unusual marks develop, or if you notice any swelling, further assessment may be warranted.
  2. Track Behaviors: Observe your daughter’s irritability over the next few days. If she continues to be fussy and you notice other concerning symptoms (like difficulty feeding, changes in her sleep patterns, or signs of pain), that would be important to consider.
  3. Check Feeding: Since you mentioned a nursing strike, ensure she’s still getting enough nourishment. If her fussiness is tied to feeding, consider different positions or environments for bottle-feeding to make it more comfortable for her.

If you're uncertain or if her condition changes noticeably, reaching out to a healthcare professional would provide you with peace of mind. Your observations and instincts as a parent are very important, so trust your judgment in watching her closely.

Concerns About Angular Cheilitis

I’m a 23-year-old woman with no history of smoking, and I’m seeking assistance regarding a health issue. Back in January, I experienced angular cheilitis three times, each episode involving a minor crack at the corner of my mouth that healed within a few days. Following the last occurrence, I became quite anxious due to saliva accumulation in that area. I found myself frequently brushing my finger along that spot. After a few days, I observed a small area forming that appeared white and had a rough texture. Eventually, I realized it was not just a coincidence, and I started taking action, but only after it became noticeably larger. To address it, I cleaned the area with a mix of alcohol and apple cider vinegar. I’m uncertain about what this issue could be, but I’ve recently begun using over-the-counter Clotrimazole cream while also keeping the area moisturized with either lanolin or petroleum jelly. Unfortunately, I haven’t noticed any improvement, and I’m concerned as it seems to be expanding. The patch continues to be rough and excessively dry. Although I can open my mouth wide without any cracks forming, I do feel tension in the skin, similar to having a bandage over that location. At times, I experience a burning sensation after thorough washing, and I’ve noticed tiny red spots appearing on the outer edges of the patch sporadically.

Unusual Heart Sensation

I’m an 18-year-old, weighing 50 kilograms and standing at 170 centimeters (and yes, I’m aware that I’m quite slender). For the past couple of years, I’ve developed a habit of smoking about half a pack of cigarettes each day. So, the other day I was lying on my left side, relaxing, when I stumbled upon an unusual sensation. It felt as though my heart was pulsating so intensely that it was almost outside my body. Out of curiosity, I pressed a bit on the area and was instantly hit with a rush; my head started to tingle, my vision momentarily blurred, and it felt as though my heart dropped. It was as if my entire system had malfunctioned. Just for context, I’ve experienced something similar before after a ketamine overdose, and it persisted for about a month afterward, occurring occasionally while trying to sleep or during random moments in bed. This current episode has me quite anxious, especially since it hasn’t happened in a while, but this time felt particularly alarming.

Experiencing Heart Palpitations Following Chest Impact

I'm a 17-year-old female who has struggled with tachycardia for several years, having been diagnosed with postural tachycardia syndrome (POTS) about five years ago, although I haven't pursued further testing because I haven't completely lost consciousness. Recently, over the past month or two, I've started to experience sensations of my heart skipping beats, accompanied by difficulty in breathing during these episodes. These occurrences have become significantly more frequent, even when I'm at rest. Five years ago, I underwent a Holter monitor test, which indicated primarily tachycardia with occasional premature ventricular contractions (PVCs), but nothing alarming was found. In early December, I was struck hard in the chest by an elbow while in a mosh pit, which resulted in some pain when taking deep breaths for a few days. My sternum became bruised and slightly swollen, and it remained tender to touch for about two weeks, but this discomfort was manageable. I still feel some soreness when stretching, although it’s not severe. Additionally, I have diagnoses of Crohn’s disease and hypermobile Ehlers-Danlos syndrome (HEDS), and I am currently on immunosuppressants. Given these circumstances, would it be advisable for me to seek medical evaluation, or could these symptoms be considered typical?
