My husband has been having intermittent sharp pains in one spot on his inner left thigh about 2 inches above the knee for the last week. It feels like someone is pinching him. It is exactly the same each time. Lasts only a second or two then goes. It happens about 30-40 times a day. He is 64 had a stent put in his heart about a year and a half ago.
Here only symptom of sharp pain in inner thigh is not enough to do any evaluation or diagnosis.  Need to check and evaluate with physical test. As well also need to know is there any numbness or burning sensation for inner thigh ? If no then nothing to worry but if yes then it might be related with nerve problem. In general I can just suggest to use hot and cold pack to have relaxing effect on soft tissue. This will also help to reduce inflammation of any and pain, for muscular pain. If the problem does not get over then do check is he having pain inn chest with breathing difficulty walking up hill.? If yes then again it can be something related to heart. If no then again don't worry. At any time for severe pain you can visit the doctor to evaluate it properly. Take care.
