Concerns After Taking Metformin: Potential Risks?
Hello everyone! I’m a 35-year-old male and I recently took a dose of 500 mg of Metformin for the very first time yesterday. Unfortunately, about two and a half hours later, I started feeling nauseated and ended up vomiting. As of today, I’m experiencing significant fatigue and weakness, particularly in my legs. There was also a moment when I felt unusually cold, accompanied by a tingling sensation in my arms. My heart rate seems to be stable at 80 beats per minute, my temperature is at 37.2 degrees Celsius, and my oxygen saturation is roughly 97 percent. Now, it’s been a full day since I first ingested 500 mg of Metformin. Should I be concerned about the risk of lactic acidosis stemming from a single tablet? I am still experiencing nausea and a slight increase in my breathing rate, along with that tingling sensation in my hands, which might be a result of anxiety. Is it possible that I’m experiencing an anxiety attack, or could a 500 mg dose truly lead to lactic acidosis?

It's understandable to feel concerned after experiencing nausea and other symptoms following your first dose of Metformin. The good news is that while side effects can occur, severe reactions like lactic acidosis from a single 500 mg dose are very rare. Let's break this down for clarity.
Key Points:
-
Metformin Side Effects: Common side effects of Metformin include gastrointestinal issues like nausea and vomiting. These symptoms often resolve over time as your body adjusts to the medication.
-
Lactic Acidosis Concerns: Lactic acidosis is a serious condition but is typically linked to higher doses of Metformin or specific risk factors such as kidney impairment or dehydration. A single 500 mg dose in a healthy individual is unlikely to cause this condition.
-
Your Symptoms: The fatigue, weakness in your legs, and tingling sensation could be related to the nausea, anxiety, or simply your body reacting to the medication rather than an indication of lactic acidosis. Anxiety can certainly cause physical symptoms, including increased heart rate and sensations of tingling.
Next Steps:
-
Hydration: Ensure you are well-hydrated, as dehydration can exacerbate nausea and fatigue. Drink water or clear fluids throughout the day.
-
Monitor Symptoms: Keep track of your symptoms over the next few days. If the nausea persists, or if you experience increasing weakness, severe fatigue, shortness of breath, or unusual symptoms such as confusion, seek medical advice immediately.
-
Rest: Allow your body to rest. It's normal to feel fatigued after such experiences. Try to take it easy while you recover.
-
Consider Anxiety: If you suspect anxiety might be playing a role, practice relaxation techniques such as deep breathing or mindfulness exercises to help manage those feelings.
-
Follow-up: If your symptoms do not improve or worsen within a couple of days, it would be wise to consult a healthcare provider for further evaluation.
Remember, it’s always best to listen to your body. If you have any concerns about your health, reaching out for professional guidance can be very reassuring. Take care, and I hope you feel better soon!

Should I continue to clean the area with soap and water, or would it be prudent to seek immediate medical attention at the ER for a professional evaluation?
Should I Seek Medical Attention?
At 22 years old, I am a female who has been on medications like duloxetine, lamotrigine, and hydroxyzine for several years. I have managed to keep my Graves' disease under control, but I have reasons to believe I may also be experiencing symptoms of POTS (Postural Orthostatic Tachycardia Syndrome). Last year, I was scheduled to consult a neurologist regarding hand tremors and the possibility of fibromyalgia. Unfortunately, I could not continue my treatment after relocating and losing my health insurance. Just 15 minutes ago, I fainted. Prior to that incident, I was feeling unwell—dizzy, my vision was blurry, and I experienced a whooshing sensation along with heat in my ears. My face and arms also felt tingly. After fainting, I experienced a heavy, aching sensation in my head, and I still have a headache now. Additionally, I’ve been waking up with headaches for a couple of days. I want to know if it's advisable to go to the emergency room. It's important to note that this isn’t my first fainting spell; I had one incident years back, which helped me recognize the signs when it started happening. At that time, I was lifting a heavy bed frame, and when I began to feel faint, I tried to sit down but stood back up to assist, and that’s when I lost consciousness. I’m unsure how long I was out, but I initially thought I was just sleeping before realizing what had happened when I regained awareness.
Seeking Guidance for My Mother's Sudden Hearing Loss Case
I am looking for advice regarding my mother's situation with sudden sensorineural hearing loss (SSNHL). **Patient Overview:** - **Age:** 48 years - **Gender:** Female - **Medical Issues:** Hypothyroidism and overweight (approximately 95 kg at the onset) - **Treatment:** Thyroid medication (25 mcg taken daily) **Medical Background:** In November 2025, my mother experienced an abrupt hearing loss in her right ear accompanied by dizziness and nausea. We consulted several ENT specialists within approximately 36 hours following the onset of her symptoms. She received a diagnosis of SSNHL but unfortunately, she did not undergo intratympanic steroid injections during the critical first 24 hours that could have aided her recovery. Despite receiving subsequent treatment, she has not regained hearing in her affected ear. **Examination Results:** - **Audiogram:** Loss of approximately 100 dB in the right ear; left ear shows normal hearing. - **Brain MRI:** A normal scan was conducted previously, ruling out tumors. - **Laboratory Tests:** Recent blood tests (including thyroid function, HbA1c, renal and liver function tests, CBC, etc.) show elevated TSH (6.73) and a HbA1c of 8.5%. We are currently preparing for a contrast MRI to eliminate the possibility of a vestibular schwannoma or nerve issues. **Current Condition:** The hearing loss persists in her right ear. She is feeling anxious about the upcoming contrast MRI, which involves gadolinium injection. However, she has started making positive lifestyle changes and has lost about 4.5 kg over the past two months, adhering to a protein-rich diet and a walking regimen. **My Inquiries:** 1. Is it still beneficial to perform a contrast MRI several months after the initial SSNHL diagnosis, considering that a normal MRI has already been completed? 2. For cases such as this—severe SSNHL with delayed steroid intervention—are there realistic prospects for hearing recovery at a later date? 3. Are there any additional tests or treatments that should be taken into account at this stage? 4. For family gatherings where loud music will be present, would high-quality earplugs or noise-canceling earbuds be a good option to safeguard her healthier ear? 5. Is it advisable for her to continue with whey protein supplementation and the weight-loss plan? 6. What should we prioritize for long-term management: hearing aids, rehabilitation, regular monitoring, etc.? I recognize that the chances of recovery may be slim, but I want to ensure we are covering all bases and that her care plan is appropriate. I appreciate any insights or suggestions you can offer. Thank you for your assistance!
Seeking Clarity on Medical Notes
Greetings, I’ve chosen to use a throwaway account to keep my medical details private from my main one. My daughter, a 3-year-old with cerebral palsy, is prescribed baclofen, gabapentin, senna, and occasionally, Miralax. She is raised in a smoke-free and alcohol-free environment. Recently, my daughter has exhibited instances of staring and being unresponsive, which we discussed with her pediatric neurologist. These episodes occurred multiple times over three weeks. Concerned about potential seizure activity, we recorded some incidents and shared them with the doctor. He advised us to schedule an EEG, which was set for the soonest available time a week later, while instructing us to call if more episodes occurred. When another episode took place, we reached out to the neurologist, who practices at a children’s hospital approximately two hours away. He recommended that we go to our local emergency room. Upon arriving there, the attending physician reviewed her history but seemed skeptical. After a lengthy wait and attempts to clarify our situation, the on-call neurologist eventually came to see us—although he showed little interest in the video evidence we provided. He proceeded with an EEG that lasted only 15 minutes during which my daughter did not have any episodes. Unfortunately, this neurologist was rather abrupt and seemed dismissive, ultimately sending us home without satisfactory answers. Now, I find myself puzzled. In the EEG report, the neurologist mentioned something called a "teddy bear sign." As I had never encountered this term before, I did some research and discovered that it may suggest that seizure activity is not genuine if the patient is in possession of a stuffed animal or similar item. Is this a legitimate observation? My daughter indeed had her beloved baby doll, which she takes with her everywhere. I fail to comprehend how this could be relevant or why it might indicate that her potential seizure activity is fabricated. I plan to reach out to her primary neurologist to gain deeper insight into the meaning of this "teddy bear sign." Thank you for your help!
Blood in Urine: Seeking Guidance
A 20-year-old female weighing 140 pounds has not been taking any medications or supplements, and has no prior or current medical conditions. Her menstrual cycle last occurred two weeks ago. While at work, she observed blood in her urine, which appeared light red but darker than pink. Accompanying this symptom, she has experienced some abdominal discomfort. Notably, there was no evidence of blood on her underwear, only when she urinated. Additionally, she felt a moment of lightheadedness upon noticing the blood, which has since subsided; she attributes this feeling to her anxiety about the potential seriousness of the situation. Given these symptoms, what could be the likely cause? She is uncertain whether to visit the emergency room or to wait until urgent care is available tomorrow for a consultation. As she recently relocated and does not have a primary care physician yet, her anxiety is heightened.
