Hi guys. I had ulnar nerve injury months ago its still there but i barley feel it. Now i got new problem which scares me , i used diclofenac gel as the doc recommended but after 10 days of useing it i got strange pain in my triceps i mean all the triceps area now i havd read that diclofenac gel can cause serious problems in vessels im could this gel did a serious damage to my arm? What to do to check if this gel did serious damage?
