my mom is 77 years old. she has leg pain tonight...lower leg on outside from knee down the through calf. it doesn t hurt if she puts no weight on it unless she turns her foot inward. it doesn t appear more swollen than other leg nor warm. she says she is experiencing muscle spasms in her calf area. she can barely walk and found a cane in her closet tonight to use. she has history of high blood pressure and had to have her left arm artery cleared twice about 8-10 years ago. worried about blood clot
