Since your cardiologist confirmed your heart tests are normal, this recurring left-sided chest and shoulder pain is likely not cardiac. Instead, it may stem from muscle tension, emotional stress, or the significant hormonal shifts your body is experiencing after a miscarriage. Your doctor prescribed Concor (bisoprolol) to help manage your fast heart rate and blood pressure, which can both be elevated by stress. Please continue taking it as directed. I gently encourage you to follow up with your gynecologist or primary care doctor to explore these non-cardiac causes.

An overdose of this amount can cause your heart rate to slow down and your blood pressure to drop, which might make you feel quite dizzy, tired, or lightheaded. Because this is a high dose, the safest and most important step is to seek immediate medical attention or contact emergency services right away. They can easily monitor your heart and keep you safe. Please consult a healthcare professional immediately so they can take care of you.

Since you have only taken desvenlafaxine for one day, it is generally safe to stop taking it immediately without withdrawal risks. However, please consult your doctor before making any changes. Sweating and heartburn can happen when starting this medication. Regarding your other concerns, daily alcohol use can increase drowsiness and worsen both anxiety and heartburn. Additionally, desvenlafaxine can sometimes raise your heart rate, which might counteract your bisoprolol. Please share your alcohol use and these symptoms with your physician so they can safely adjust your treatment plan.

Yes, stopping your Concor 5 (bisoprolol) suddenly can definitely cause severe headaches. Bisoprolol is a beta-blocker, and abruptly discontinuing it can lead to a "rebound effect," causing blood pressure changes that trigger intense headaches. This explains why your usual migraine treatments aren't helping. It is very important not to restart or change your medication without medical guidance. Please contact your prescribing doctor or a healthcare professional as soon as possible. They can help you safely manage your heart rhythm and guide you on how to ease these headaches safely.

Sometimes, medications like Concor (bisoprolol) and PPIs (proton pump inhibitors) can manage symptoms so well that tests appear normal. Alternatively, the ongoing chest and arm discomfort could stem from non-cardiac sources, such as muscle strain, nerve sensitivity, or esophagus spasms that do not show up on a standard camera test. Because you are still experiencing these symptoms, I gently encourage you to follow up with your doctor to explore these other possibilities. Please seek immediate emergency medical care if your pain worsens, spreads, or is accompanied by shortness of breath.

It is very common for a fever and infection to temporarily increase your heart rate and blood flow, which can cause a new temporary murmur or make your known mild valve leaks louder. This is often just a temporary reaction to being sick. However, because you have pulmonary hypertension and an enlarged heart chamber managed by Candace (candesartan) and Concor (bisoprolol), it is important to be safe. Once your fever and cold have cleared, please have your doctor listen to your heart again. They can determine if a follow-up ultrasound is needed to ensure your heart remains stable.
