After a yoga, including back bends, i was relaxing in a seat. upon standing my hip & glute were sore. there is a bump right around my bone at my hip in the left iliac region. tenderness although i feel similar lump(not swolen) on my right?

Need to examine: It is not clear if there is any organic issue, other than soreness from exercise. Take Tylenol of the soreness, no more than 4 g/day, no alcohol. If it does not get better in a couple of days, skip exercising for 4-5 days. Have a healthy diet, drink plenty of water daily so your urine is mostly colorless, have safe sex, no tobacco alcohol weed or street drugs. Wish you good health!
