Hi,Dear,Welcome with your query to HCM.
Studied your query in full depth of its details.Reviewed it in context of your health concerns.
Based On the facts, You mostly seem to suffer from-
Oschgood Shlatter's disease , which is patellar
tendinitis with tibial tubercle apophysitis-as you have no bony / softtissue abnormality.But do have lump which pains on pressure.This could also be-Retro-Patellar Bursitis
Treatment -
Would be Inj Kenacort- with a interval of 3-6 weeks x for 2-3 sittings would give total resolution of such a problem.
Tab NSAIDs-Motrin-
Tab Vit D3 +Calcium would expedite the healing process and the lump feeling under the skin on the leg.
This reply would help you to plan further treatment soon with your treating doctors.Best of Luck and early recovery.
