As a possible fibromyalgia patient, I find that working out with weights is beneficial to issues such as chronic back and neck pain. But while doing bicep curls with a 25 lb dumbbell I would experience greater pain in my right bicep than my left. The bicep curls aren't even a necessary exercise but I tossed them into the workout anyway. I thought pain was an ordinary part of any workout, so I kept up the routine, but eventually something went wrong in my right arm. And since the pain would never go away despite the fact that I discontinued the curls, I finally had to go see a doctor.
When the incident occurred it was so painful that I had to drop the weight immediately and apply ice packs and heat to the sore spot. The area is right in the crook of my arm where there is a large bicep tendon. A doctor fiddled around with the tendon for a while and hemmed and hawed over whether there might be a cyst present. He recommended a $2000 MRI. I recognized this as a common doctor scam and turned down the MRI. I just think that if there was a cyst in this particular spot then palpating the area would detect it immediately, especially with his 20 years of experience. And all I feel in that spot, besides the tendon, is a rather large vein right beside it. I would hope he can detect the difference between a hard cyst and a soft vein.
The pain has been there for 10 months now with no end in sight. When I switch to using my left arm for lifting things, I have found that my right bicep has started to atrophy. I have taken anti-inflammatories but with no instructions as to when to take them, how much to take, or when to stop them. Heat and cold packs are beneficial, but then I will simply reinjure the tendon during my daily routines.
