I just finished up my first round of steroid treatment this week and have noticed a very painful situation happening. A couple or three times now Ive been woken up with severe pain in my chest. Like the pain associated with getting kicked in the chest, or falling and getting the wind knocked out of you. Its that same pain minus any kind of impact. My rib cage feels tight too. Is this MS hug? Does anyone have any recommendations on what I might do to lessen the pain. Ive notice Vics vapo rub does help a little. But I'm hoping there might be something that works better, as this is only a slight improvement that works for a very short time.
