Hi - Last Monday, I woke up with terrible pain in right shoulder and general weakness in the body. Same thing happened, Tues and Wed. I exercised by using 3lbs dumb bell in Wed and may have caused costochondritis according to the doc. I have to stop his med (mobic) for 2 days because of hyperacidity. Saturday went well for me. Then on Sun night, while walking (15 mins) and standing (30 mins) in church, I felt lightheaded to the point that I felt I m gonna pass out. Coming home later in 20 mins, I have terrible pain in right shoulder again until Mon morning (Asia time). It radiates to my right side of head/face feeling numb. I am worried I might have the shoulder pain regularly and worried about passing out somewhere. Thanks for any advice in advance!
