Hi , I was sitting down about a month and a half ago all of a sudden I got a really sharp pain in my lower left side of the back that quickly starting striking pain by my heart . I called 911 they treated it as a heartattack , I thought that was what was happening to me . The hospital said I had pleurisy and sent me home with ibruprophen 600 mg about a week it was feeling like it was gone . I slightly felt it ever now and then . Tuesday night I felt like I couldn t breath and the pain on my back , side and chest came back but not as severe as the first time . I went to a local doctor he listened to my lungs said it was pleurisy , and bad bronchitis . He gave me Levofloxacin , methylprednisolone and a cough syrup with Tylenol 3 in it . I took the cough syrup the first night made me feel sick so I stopped taking it . Took the Methylprednisolone first dose which was 6 pills at one time I got agitated . So I stopped taking that , now im only taking the Levofloxacin . Id like to tell you before I continue the medications I am prescribed on a daily basis .. Xanax 2mg 3xs a day , Zoloft 150mg once daily , Percocet 7.5/325mg 4 times a day , about 2,000 mg of fish oil daily and omeprazole for acid reflux . My question and concern is , even tho taking all this medication my back , side and under the chest bone is still hurting . And I feel very weak and tired ... Could this be a more serious case of something else ? Also have been having striking headaches ..
