Hello.
The symptoms you have described may not be part of a panic attack. Typically, symptoms of panic attack last for those 5-10 minutes of the attack.
The pain in the arm and the chest tightness could be part of a generalized anxiety spectrum. If you have had a traumatic experience in the past, panic attacks may be accompanied by anxiety.
You should play safe keep a journal of the events while you are actually having the pain. You should also consider another class of medicines, which are specifically meant to treat panic attacks. Paroxetine is good and effective and probably the mainstay of panic attack treatment.
Regards
