I think it is trapped lactic acid. I try and massage it out and it does move but no pain killers get rid totally. I too take tramadol . They give me loads of energy. My dr thinks I am mad! But they do! I cannot take the after 11am as I will be awake all night, but I am able to do some work for a while but the pain after is b awful! I had a practitioner who,used to get rid of the pain in my upper arm, and he said it was lactic acid. I wish I remembered what he did!

Yes , my arms get very sore . I take long hot baths with Epsom salt. I wrap the heating pad around my arms and alternate it. I take tramadol,also.

I wrap heating pads around my arms .

It worked and lasted 4 to five hours. The pain reduced significantly. Much better than pain killers. I am hoping the massaging it in will aid relief as well.

I ordered it of Amazon. My only place to shop. Really pleased with it!
