I am 18 years old, one month ago, i started with pinching pain in my left chest, which slowly spread to right side also. And became severe day by day. 15 days ago, I got ecg, chest x-ray, blood tests, d-dimer test, rt-pcr test done. All the reports were absolutely fine, only my vitamin D was deficient. I have no other problem other than some bowel problems. I am taking vitamin D supplements but then also till today I experience pinching pain in my chest atleast 2-3 times a day. The location of the pain keeps on changing in the chest, but most oftrn it is on the upper left side of the chest. Sometimes, the pain is severe and sometimes not. The pain lasts for 3-5 minutes. I also took gastric capsules(pan l) for 15 days but no releif! Kindly help.
