Comments from related studies:

  • From this study (3 weeks ago):

  • My doc just switched my GERD meds, and I just started the nerve meds too. I also take vitamin supplements, C, D, B, krill oil, and calcium daily.


  • From this study (1 month ago):

  • I have a bartholin cyst on the left side and there are small, canker sore like abrasions on it. Only hurts when I touch it or urine touches it. No discharge or itching. Tested negative for hsv 2 but positive for hsv 1


  • From this study (2 months ago):

  • After an elbow injury I have received x-rays and been to doctors and they believe it is just a contusion to the elbow. The pain continues to increase, it has become constant pain in the elbow (where the injury occurred), down to my wrist, and up to my shoulder. I cannot move it without sending shooting pains that immobilize me down to my fingers and up to my shoulder. I have been having it in a sling, and icing it and taking ibuprofen and tramadol which only barely dull the pain.
    Is this really only a contusion? How long should I wait before seeking more medical help
