I brought my husband to er dec 19 2013 due to chest pain. He said he had a big lunch but still took him to er, dr said blood enzymes elevated so they did angiogram next day. Dr said no major blockage and did not put any stent. He was given clopidogrel 75 mg, atorvastatin 20 mg, metoprolol 50 mg and losartan 50 mg. last aug he had parathyroid surgery and was given tums to take 4 tabs a day and alendronate for the osteoporosis. Recently....he has been having nose bleeds and stomach bloating and gas......shld we go to the cardiologist so he can stop the clopidogrel and just aspirin instead. He also has been having severe knee joint pain. Im very worried and anxious. I appreciate your advise.
