What causes tightness in the hamstring when I sit down?
Patient: My symptoms are: My left hamstring started tightening up a few weeks ago, especially when I sit down. This has been followed by pain in my knees (burning at times on sides) and tightening of my calfs. Sometime stiffening up so much that it is hard to walk. I just turned 56, but pretty muscular for my age. My only medical condition I had was after my physical a few weeks ago my TSH level was 7.5 so Dr. has increased my thyroid medicine from .05 to .1. Hopefully I do another thyroid panel in a week or two. I have been on thyroid meds for 4 years. Not sure this is cause although I do know one symptom of hypothyroidism is muscle pains. Doctor: Hello,  It can be due to muscular pain as in pulled muscles. As a first line of management you can take analgesics like paracetamol or Diclofenac for pain relief. If symptoms persist you can consult an orthopaedician and get evaluated.  Hope I have answered your query.  Let me know if I can assist you further.
