Thanks for writing in.
I assume you had the pain in the left side of your chest and/or abdomen. Correct me if I am mistaken. If the pain is in your chest, it could be due to a muscle sprain
or some trauma. I would suggest that you use hot compresses, use diclofenac
spray and take Tablet motrin for the pain as and when required.
If the pain is in the abdomen, it can be due to gastritis
or some infection. I would suggest you take frequent meals, eat homemade food, take Prevacid
OTC once a day 1 hour before meals. If the symptoms persist, you should also see your physician for ruling out other causes like infectious mononucleosis
I would like to reassure you that the bleeding from the gums and this pain are not related at all.
Hope this helps.
