<s>[INST] Hi, I am 25 years old and I recently had a bump along my lower back that seems tense sometimes. Along with episodes of swelling in my left foot and shin and my penis and groin area also experience swelling but no pain on either. I recently stopped working out, but prior I did do exercises that consisted of heavy dead lifts. Do you know what this could be a result of? [/INST] Hi,Dear thanks for the query to HCM.Cause  -for-a-the  lump on lower back -a clinical check is required from your family doctor as the information from the query is non-commentable as its incomplete and very vague.Plz call back again with more information. And I would love to help you out from the complex query worrying you.So check up with family doctor and update that clinical check up data to me ASAP.Hope this would help your worry to take proper steps for health.Wellcome again if you have any more query in this regard.Have a Good Day. </s>
