Lenore continued to have health difficulties, visiting medical centers around the country but unable to get a clear diagnosis. One specialist attributed her problems to a failure to absorb sufficient calcium, for which she was given once-a-week shots. She was found to have several food allergies and spent time at Chicago's Swedish Covenant Hospital in 1967. She suffered an injury outside her house around 1967 and another the next year when she fell and suffered a shoulder dislocation that turned into bursitis. During October 1968 she was hospitalized at Barnes-Jewish Hospital in St. Louis, seeing a bone and mineral specialist.
