Concerns About Strep Throat and Cefdinir Effectiveness
Four days ago, on Sunday, I began experiencing a severe sore throat. By Monday morning, I noticed white spots on my tonsils, leading me to believe I might have strep throat. I visited a healthcare professional who noted the symptoms seemed indicative of strep, but the rapid test returned a negative result. The doctor suggested it could be a false negative, speculating instead that I was dealing with a bacterial sinus infection. She prescribed a 300mg dosage of Cefdinir, which I started taking at 6 PM on Monday. As of now, it’s Wednesday at 11 AM, and I have completed four doses of Cefdinir; however, I have seen no improvement in my symptoms. I had no fever initially on Sunday or Monday, though I did develop a mild one on Tuesday. It's worth noting that I have been taking naproxen and ibuprofen, which may have impacted my fever levels. My throat continues to be extremely painful, and my tonsils look worse than before. I am trying to determine if Cefdinir usually requires more than 40 hours to show any improvement or if it would be wise to schedule another appointment with my doctor to discuss my ongoing issues. She mentioned that I should be non-contagious after 24 hours and that I should be able to resume work by now, yet I still feel as unwell as I did two days ago. Thanks for any input!

It’s understandable to be concerned when you aren’t seeing improvement despite starting antibiotics like Cefdinir. Here’s a summary of the key points and what you can do next:
Main Points:
- Duration and Efficacy of Cefdinir: Antibiotics can take a few days to show noticeable improvement, but if symptoms worsen or no improvement is seen after about 48-72 hours, it's worth reconsidering.
- Potential Misdiagnosis: While you might be experiencing symptoms consistent with strep throat, a negative rapid test suggests that another cause may be at play, such as a viral infection or a different bacterial infection.
- Persistent Symptoms: Given your continued severe sore throat and worsening tonsils, a follow-up is prudent.
Explanation:
Cefdinir is generally effective in treating bacterial infections but can take time, sometimes up to a couple of days to start alleviating symptoms. However, if you don’t feel any better after 48 to 72 hours of antibiotic treatment, it may indicate that the infection is not responding to the antibiotic or that a different underlying issue exists.
Next Steps:
- Continue Monitoring: Keep track of your symptoms, especially if they worsen or if new symptoms arise, such as increased fever, new rashes, or difficulty swallowing.
- Pain Management: Continue to use over-the-counter pain relievers like ibuprofen (if you're tolerating it well) to help manage throat pain, but do so as directed on the label or by a healthcare professional.
- Hydration and Rest: Stay well-hydrated and get plenty of rest, as these are essential for recovery.
- Follow-Up Appointment: Given that you’ve not seen improvement after four doses, contact your healthcare provider promptly to discuss your symptoms. They may want to re-evaluate your condition, possibly consider a throat culture for strep, or explore other treatment options.
Please rest assured that there are options available to help you feel better, and it’s always okay to seek further medical advice if your symptoms are not improving. Take care!

Increasing Pain in the Sternal Area
A 26-year-old female, standing 5 feet 2 inches tall and weighing 150 pounds, is seeking insights into her health condition. **Current Medications:** birth control and Allegra. **Past Medical History:** includes irritable bowel syndrome with constipation (IBS-C), bilateral cubital tunnel syndrome that required surgical intervention at ages 17 and 18, and minor kyphosis. For the past year, she has experienced considerable stiffness, along with clicking and popping sensations, accompanied by mild discomfort located at the costosternal junction, particularly around the second to fourth ribs, with greater intensity on the left side. Recently, during the last three days, she noticed a notable increase in pain on the left, to the extent that it occasionally causes a sharp sensation that temporarily immobilizes her. However, once she changes her position, the pain becomes more bearable. Notably, she is not experiencing any shortness of breath. The pain appears to be triggered by movement and can be replicated, leading her to believe that cardiac or pulmonary issues are unlikely. Attempts to alleviate the discomfort with a lidocaine patch have been largely ineffective, although she has found some slight relief with ibuprofen. This situation appears to align with typical presentations of costochondritis; nonetheless, she acknowledges that such symptoms typically resolve within a few weeks, while hers have persisted for an entire year. She has encountered information suggesting that chronic costochondritis might point to rheumatoid disorders, and she is uncertain about the validity of this claim. Given her earlier struggles with ulnar nerve entrapment, which occurred during her teenage years, she is contemplating whether this pain warrants further medical evaluation. Currently, she lacks comprehensive health insurance, and she wishes to avoid any extensive diagnostic processes if they are unlikely to yield actionable results. However, if there is a possibility that her symptoms could indicate a more serious condition, she is prepared to follow through with recommended evaluations. Thank you for your assistance!
Persistent Discomfort and Sensitivity in My Leg Since July 2025
I am a 19-year-old female diagnosed with PCOS, and I occasionally take hydroxyzine, a medication I only use a few times each month. On July 12, my leg from the mid-thigh down experienced a strange sensation—either numbness or heightened sensitivity. By July 14, the situation prompted a visit to the emergency room. The medical staff informed me that I had an inflamed nerve in my back. They prescribed anti-inflammatory medication and released me. However, since that day, I've noticed my right leg has felt unusual. After walking for more than half an hour, continuing to move becomes quite challenging. Riding a bicycle for just a few minutes causes burning sensations in my knee and weakness in my legs. At present, my knee and ankle are the areas that feel the most sensitive. Following any extended walks, the discomfort in my leg can last for up to three days. Additionally, I experience a sharp, intense pain in my hips, particularly in the upper thigh region and deep near the hip joint. It is important to note that I cannot be pregnant, as I practice celibacy. Visually, there are no noticeable differences between my affected leg and the other one. However, I experience pain when pressure is applied to my right ankle, and excessive movement worsens the discomfort. Otherwise, to an outsider, there appears to be nothing wrong at all with my leg.
Experiencing Severe Discomfort - What Are My Options?
Age: 35, Height: 5'2", Weight: 61 kg. I have been suffering from intense discomfort located beneath both of my ribs, particularly a sharp pain deep under my left rib cage. A significant medical event occurred on November 25 when I underwent gallbladder removal. This morning I experienced diarrhea, which has since improved after taking loperamide. However, about an hour ago, I was abruptly awakened by significant pain radiating under my ribs. Additionally, I've experienced minor nausea that hasn’t alleviated my symptoms. I took co-codamol roughly three hours ago for pain relief, but it has proven ineffective against the current level of pain I'm enduring. What might be causing these symptoms? I live in the UK and I'm hesitant to utilize emergency services unnecessarily. Yet, given that co-codamol hasn't alleviated my discomfort, and I have a demanding 12-hour shift ahead tomorrow, what steps should I take next?
Experiencing Discomfort in My Left Armpit
I realize this may sound odd, but I'm feeling unwell and thought I'd seek some advice regarding my symptoms. A few days ago, I began experiencing cold or flu-like symptoms, which isn't unusual for me as I seem to catch these colds every month. However, what is out of the ordinary this time is the intense pain in my left armpit and left arm. The discomfort is quite pronounced, ranging from about a 6 or 7 on the pain scale at its worst, while averaging around a 4. Typically, I experience muscle soreness in both armpits and around the lymph nodes in my neck, but this sensation feels distinct. It’s difficult for me to articulate, but it seems to be an internal pain rather than muscular. The pain appears to originate from my armpit area, closer to my back, yet it radiates down my arm towards my pinky finger. I no longer have a fever; my main symptoms now are congestion and a general feeling of malaise. I thought it was best to reach out for some insights regarding this issue.
Severe Throat Discomfort
Hello! I've been experiencing a severe throat discomfort that intermittently appears. This issue generally arises as I begin to recuperate from an illness, typically persisting for approximately three weeks to a month. During the initial episode, I struggled to turn my head or move my neck at all. While residing in college dorms, the campus health staff repeatedly speculated it was mononucleosis, despite my negative test results on several occasions. This occurred around October or November. The next episode unfolded while I was traveling over the summer. I encountered the usual travel-related illness due to my historically weak immune system, and this prolonged sickness lasted about a month before the throat discomfort returned. I eventually visited the emergency room for relief, but they offered no solutions. They assured me I was fine based on negative strep tests and a clean bill of health for "other conditions." They merely provided ibuprofen, acetaminophen, and Benadryl to assist with sleep. Just two weeks ago, I fell ill again, recovered swiftly, but then woke up yesterday with a throbbing sore throat. My neck aches, and I can feel that my lymph nodes are enlarged. I can’t shake this ominous feeling… To add some context, I’ve observed a pattern; each instance of these illnesses coincides with periods of significant stress in my life.
