Hello, I noticed the other day a lump on my inner thigh it about 8inches above my left knee cap and the size of a golf ball but not like a complete sphere If you get my meaning, dosent hurt, no color, is most visible if I squat down it then seems to buldge out..I checked my other thigh for comparison and there seems to be the same part/similar but without the raise lump..I would say its between my sartoiousr (8 inch up from the knee) and the Vastus medialis muscles if that make sense? Also left hamstring is rather tight also as I,ve been sat working whilst learning to reach for items so putting extra strain on the left hamstring I m a 45 year old male in above average health I d say Thanks
