I've been noticing this tingling sensation on the left side below my chest and sometimes at my back. It's not constant but usually happens when I'm lying down and occasionally when I'm sitting. I checked my blood pressure, which was 12381, and when I'm relaxed my pulse rate is around 60, but sometimes it drops to 55. Do you think this is something to be concerned about?

Tingling sensation on the left side below the chest and at the back could be due to nerve compression or irritation. Since your blood pressure and pulse rate are within normal limits, it is less likely to be related to a cardiovascular issue. However, it is important to rule out any musculoskeletal or neurological causes. I recommend taking a muscle relaxant like Flexeril (cyclobenzaprine) 5mg to help with any muscle tension that may be contributing to the tingling sensation. Additionally, you can take an anti-inflammatory medication like ibuprofen 400mg to reduce any inflammation that may be affecting the nerves. If the symptoms persist or worsen, it is advisable to consult a healthcare professional for further evaluation and management."
