 [ Symptoms ] are there any sleep aids that a pregnant woman can take [ Disease ] so sorry to hear your husband is going through this nagging rib pain is no fun yes his symptoms certainly could be caused from leaning on that fence railing while fishing i hope he reeled in a big one for his trouble since he is had all the usual heart testing and was told his heart was in good shape i am going to guess he is got a case of costochondroitis or an injury to the cartilage between his ribs leaning against a sharp object such as a fence railing could cause a mild tear or irritation of the rib cartilage rib cartilage will repair itself eventually unfortunately it may be mighty ouchy until the healing is finished your husband can take over the counter pain relievers such as anti inflammatory medication like ibuprofen naproxyn or plain aspirin for the pain hope this helps
